play machine slot A play poker money online of research has examined how the unique presentation of near-misses and the use of a stop button in multiline slot machines impact erroneous cognitions related to the perception of skill and agency during play.
We recruited 132 gamblers from a casino in Ontario.
They played two versions of a slot machine simulator: one with a stop button and one without a stop button.
We predicted more robust physiological SCRs and longer PRPs to wins in the stop button game.
We also predicted that near-misses encountered in the stop button game would trigger greater levels of arousal and frustration in players, as indexed by larger SCRs, and greater force applied to the spin button to initiate the next spin.
Erroneous cognitions pertaining to the stop button and near-misses respectively were assessed following play.
Results showed that a small but meaningful percentage of players held erroneous cognitions about the stop button 13.
Players depressed the spin button harder, and had larger SCRs for all outcomes when using the stop button.
Players also paused longer for near-misses in the game involving the stop button.
Our findings converge to suggest that the stop button encourages an erroneous perception of skill in some players, and consequentially impacts how such players perceive their outcomes in multiline slot machines.
Slot machine gambling has been prevalent in Canada since its legalization in 1985 Campbell et al.
Since then, slot machine games in Canadian casinos have evolved to possess an impressive array of design types and different features to entertain players.
Indeed, such continuous evolvement partially explains why they have been able to maintain player interest across the decades.
Despite their potential for entertainment, slot machines have been cited as being the most problematic form of gambling Williams and Wood.
In fact, they typically generate more than 24% of casino revenue Williams and Volbergand their increasing availability is positively linked to the prevalence of problem gambling in Canada, currently estimated at approximately 3% of the population Williams et al.
In 2010, a problem gambling helpline in Ontario received approximately 2000 calls.
The vast majority of these calls involved concerns about slot machine gambling Centre for Addiction and Mental Health.
In one particular study, 80% of high-risk problem gamblers cited slot machines as being their primary game of choice Ladouceur et al.
Given this link to problem gambling behaviour, it is imperative to explore how such problems may manifest at the origin of play.
Cognitive biases have been shown to influence the onset of problem gambling behaviour.
Such skill-oriented cognitions are primarily defined by an internal locus of control, such that players psychologically attribute outcomes of an event to their personal control or their own abilities.
Such thinking styles ultimately lead to disadvantageous decision making in gambling, as evidenced by increased bet sizes, longer gambling session lengths, and in some cases, chasing behaviour Walker ; Dixon ; Chóliz ; Lim et al.
Although it is known that problem gamblers are the most vulnerable to adopting skill-oriented erroneous cognitions both during gambling, and outside of the gambling context Orgaz et al.
One particular slot machine feature is the so called near-miss.
In a simple three-reel slots game a classic near-miss would involve two jackpot symbols on the payline, with the third just off the payline.
Many players fail to appreciate this and will interpret a near-miss as being closer to a win than a regular loss Dixon and Schreiber.
Others appear to interpret near-misses as indicators of skill at slots or as a harbinger of an upcoming win.
One goal of this study was to assess how common such erroneous cognitions are among frequent gamblers, and whether such beliefs about near-misses are related to problem gambling.
It has been suggested that certain erroneous cognitions in chance-based games surface as a function of game features that foster active interaction by the player Langer and Roth ; Wagenaar.
Normally, depressing the spin button on a slot machine causes the animated reels to spin in unison for a brief duration, then each reel will slow and eventually come to a stop with the leftmost reel stopping first followed in sequence by the remaining reels.
By pressing the stop button while the reels are spinning, however, the animated reels will come to a stop far more quickly than in games without a stop button.
Importantly the stop button does not permit players to manipulate where the reels will stop.
In fact, the stopping positions of the reels are actually determined by a random number generator as soon as the player presses the spin button.
Use of the stop button merely causes the reels to settle into their already-selected positions more quickly Harrigan and Dixon.
What makes the stop button potentially problematic is that it may not be apparent to players that these buttons only impact the speed of play.
Some players appear to think that their interactions with the stop button have an impact on where the reels stop and hence the outcomes of the spin.
Ladouceur and Sévigny examined how the stop button contributes to the illusion of control while gambling.
Players played two sessions on a video lottery simulator: one that included the use of the stop button, and the other session without the stop button.
A majority of players endorsed the belief that the stop button influenced where the reels stopped, with some even expressing the belief that there was actually a skill to using the stop button.
Presumably such skill involved the erroneous perception that by pressing the stop button at just the right time the reels could be made to stop over winning outcomes.
Crucially, in this study players chose to play twice as many spins when they had access to the stopping device compared to the game without a stop button Ladouceur and Sévigny.
This suggests there may be a problematic relationship between the presence of the stop button, erroneous cognitions and play duration.
In Ontario, steps have been taken to dispel erroneous cognitions involving stop buttons.
All slot machines with stop buttons have signage on the machine that explicitly tells players that stop buttons only affect the speed of play, and do not influence the game outcomes.
One goal of this study was to ascertain if at least some players recruited from these casinos who should be familiar with this message play aristocrat poker machines free nonetheless still hold erroneous cognitions about the stop button.
Although the stop button does not allow players to manipulate the stopping position of the reels, several lines of research suggest it may grant players a sense of personal agency during play.
The second reel contained this same icon along with five other different icons.
If the second reel stopped so that the matching banana icon on reel two was horizontally adjacent to its twin on reel one the player won.
If the second reel stopped so that a different symbol appeared next to the play icon e.
There were three types of key outcomes: wins adjacent matching iconsregular losses where the required matching symbol on reel two stopped in a position relatively far away from the winning alignment, and a near-miss where the matching symbol stopped close to—but just off the winning alignment.
Typically, because the near-miss conveys a thwarted goal, they are notorious for being physiologically arousing and frustrating Reid ; Brown.
In this two-reel slot machine task, personal agency was manipulated by either having the computer select the play icon, or alternatively having the player select this to-be-matched icon.
When players encountered a near-miss, regardless of condition, they experienced negative affect.
However, those in the personal agency condition experienced significantly more negative affect than when the computer selected the play icon Machine games slots play free online et al.
That is, near-misses under the condition of agency were perceived as a form of feedback confirming the adequacy of game icon choices Clark et al.
Of equal importance, even though near-misses were more aversive in the personal agency condition, they nonetheless triggered the greatest urge to continue playing game.
The Current Study In the current study we sought to assess whether the stop button would be capable of imbuing players with a sense of agency during play.
If players do indeed misinterpret the stop button as a skill-device allowing them to having some influence over outcomes then it should, as in the Clark and colleagues study, make near-misses more frustrating.
We could then replicate the important sense of agency shown by Clark and colleagues, but be able to attribute this agency to a feature that is actually available on most modern slot machines.
Rather than interrupting players during play to poll their frustration levels, we chose to use measures that could capture their emotional state without interrupting play.
Moment-to-moment changes in arousal due to hedonic pleasure and frustration can reliably be quantified by changes in skin conductance responses SCRs e.
Slot machine research has consistently shown that near-misses trigger more robust SCRs following their delivery than regular losses Clark et al.
In addition, we have shown that near-misses trigger even larger SCRs than small wins Dixon et al.
When players spin and lose in a continuous game like slots, players tend to immediately initiate the next spin Dixon et al.
Conversely, winning in slots play is characterized by significantly longer PRPs as players stop to mentally celebrate reward attainment Dixon et al.
The relation between PRPs and near-misses is somewhat controversial.
Two studies using small student samples showed that PRPs for near-misses were significantly longer than the PRPs for regular losses and more akin to the PRPs for wins Dixon and Schreiber ; Belisle and Dixon.
By contrast, two studies that included larger community samples of high frequency slots players including problem gamblers showed that although near-misses generated far larger SCRs than regular losses the PRPs were more info equivalent to regular losses Dixon et al.
A relatively novel means of measuring arousal due to excitement and frustration involves measuring the force applied to the spin button following various outcomes.
In a study of 56 regular gamblers recruited from a casino conducted by Dixon et al.
We assumed that such forceful spin initiations were attributable to the frustration of the near-miss.
In this same study, an unexpected finding was that players also applied large forces following large wins—a finding we retrospectively interpreted as an indication of increased arousal due to the excitement caused by the big win Dixon et al.
Although we have used force to measure arousal before in this one relatively small scale study, we hoped to replicate the effects of near-misses and salient wins on force responses in a study with a larger sample size.
Most research on slot machine near-misses has involved games where players hope for multiple matching symbols to fall onto a single horizontal payline.
In modern casinos, however, the most heavily used slot machines are multiline slot machines where players wager on multiple lines at once.
Many of these lines involve zig-zag combinations.
Their complexity at first blush would seem to preclude players even noticing near-misses.
Recently, however, research has shown that near-misses can impact players in these multiline games Dixon et al.
In the Dixon et al.
Horizontal triplets are unusual in that these special symbols only appear on the third, fourth and fifth reels.
When horizontally aligned, they form a familiar three-part object that signifies a relatively large win.
The top left hand panel of Fig.
The top right panel shows an example of a 100-credit horizontal triplet win.
In our simulator and in the game it was patterned after the low-level visual features in the horizontal triplet e.
The combination of such low-level visual features and auditory signalling made these horizontal triplets quite salient, causing wins involving the horizontal triplet to generate significantly larger SCRs and longer PRPs than standard-game wins e.
Crucially, horizontal triplets were capable of triggering near-miss effects.
An example of a near-miss in the horizontal triplet is shown in the lower right panel of Fig.
In this study players reacted to these horizontal triplet near-misses with larger SCRs than regular losses, and applied more force to initiate the next spin than regular losses.
Thus, another specific goal of this study was to replicate these effects using a larger sample of gamblers.
First we sought to replicate the important results of Ladouceur and Sévigny which showed that at least some players held erroneous cognitions related to the stop button.
By combining aspects of Ladouceur and SévignyClark et al.
Importantly, since the vast majority of players prefer multiline over single line games Livingstone and Woolley ; Templeton et al.
We had players play two sessions on our simulator: one with a stop button feature, and the second without a stop button feature.
If the use of the stop button evokes a sense of personal agency in players, then we would expect more robust physiological SCRs and longer PRPs to wins in the stop button game.
Similarly, we would expect that near-misses in games where a stop button is employed would trigger greater levels of arousal and frustration in players, as indexed by greater levels of SCRs, and greater force to initiate link next spin.
Participants A total of 132 participants 76 males, 36 females were recruited from a local casino in the city of Brantford, Ontario.
Participants were first asked to complete a pre-screen survey to ensure that participants: 1 Were over the age of 19, 2 had gambled on a slot machine at least once in the last 12 months, and 3 were not in treatment for problem gambling.
Participants failing to meet these criteria were excluded from participating.
Participants included experienced slot machine gamblers between the age of 19—86.
Average age of participants was 55.
Participants were excluded if there was any technical difficulty with the physiological data, survey data or if participants withdrew from the study.
Apparatus Slot Machine Simulator Participants played a five-reel multiline slot machine simulator modelled after a commercially available multiline slot machine game.
Like the commercially available game on which it was patterned, losing outcomes where the player lost all of their wager were followed by a complete absence of feedback no animations, no sounds.
Winning outcomes where the slot machine paid out more than the wager were accompanied by animations highlighting the winning line sand auditory feedback in the form of winning jingles, with the length of the auditory feedback proportional to the win size.
Even though these were net losses to the player, the simulator, like commercially available slots, accompanied these losing outcomes with celebratory feedback.
The frequency of these outcomes 27% were comparable to the rates for these outcomes in the commercial game.
Sessions were played in blocks of 250 spins comprised of 35 wins, 67 LDWs and 148 losses.
Among the 35 wins, there were 6 wins involving the highly salient horizontal triplet shown in Fig.
For comparison, there were 6 wins involving the gramophone symbol also shown in Fig.
This comparison stimulus was thought to be less salient since its features caused it to blend into the array rather than pop-out of the array like the horizontal triplet Dixon et al.
The horizontal triplet wins and the gramophone wins were each worth 100 credits.
Losses included 88 regular losses, 30 near-misses involving the gramophone, and 30 near-misses involving the stereo horizontal triplet.
These counters are shown in Fig.
Players activated spins using a modified mouse equipped with a force transducer shown in Fig.
To initiate a spin, players simply pulled on the button.
Players could activate the stop button by pulling on the external button while the reels were in motion.
This would cause the reels to stop on the predetermined outcome more quickly than had the stop button not been pulled.
A depiction of the five-reel multiline simulator used in the current study patterned after a commercially available slot machine A modified mouse was placed facing away from the player so they could feel the button, but not see it.
Spins were initiated by pulling on the mouse button.
The simulator was configured to send event markers to an ADInstruments Powerlab for each spin initiation when the player would press more info spin buttonstop button deployment, and outcome delivery e.
Force A modified button See Fig.
Output from the force transducer was translated to a millivolt signal recorded by the Powerlab.
Participants were instructed to limit movement of their left hand while playing the slot machine simulator in order to minimize contamination of the SCR data.
SCRs for each outcome were calculated by defining a 3 s window beginning 1 s after the last reel stopped moving i.
SCRs for each outcome were calculated by taking the peak skin conductance within this window and subtracting the skin conductance level value at the beginning of this window.
As per the recommendations of Dawson et al.
For PRPs, force and SCRs the first and last trial in each 250-spin block both regular losses were not analyzed.
Materials Pre-experiment Questionnaire Participants first completed a questionnaire asking about demographic information e.
Problem Gambling Severity Index The problem gambling status index PGSI; Ferris and Wynne was used to assess gambling-specific demographic information e.
PGSI scores were derived by summing the responses on the nine items.
Participants were stratified using the following mappings: 0 as non-problem gamblers, 1—4 as low-risk, 5—7 as moderate risk and 8 or more as problem gamblers.
Participants rated how much they agreed with each statement on a 7-point Likert scale, with 1 representing Strongly Disagree, and 7 representing Strongly Agree.
Game Experience Questionnaire For purposes external to the goals of the current study, players reactions to the games they had played were measured using the in-game version of the gaming experience questionnaire GEQ; IJsselsteijn et al.
Depression Anxiety Stress Scales The short version of the Depression, Anxiety and Stress Scales DASS-21; Henry and Crawford was also assessed for purposes peripheral to the current investigation.
Design Participants played two different slot machine games on the simulator.
Both games consisted of 250 spins.
Players bet one credit on each of nine lines.
In one game the stop button was enabled.
In the other game the stop button was disabled.
The order of game-type presentation was counterbalanced.
Procedure Once participants were confirmed to have met the eligibility criteria and provided consent, they were seated at a station with 2 adjacent laptops one for the simulator and the other for answering survey questions.
The models of both laptops used were Lenovo G530-444625U.
Participants first completed the demographic items, and the PGSI.
Afterward participants were introduced to the slot machine simulator.
Participants were shown the pay-table and told that they would be betting one credit on each of nine lines.
They were told that they could win by lining up identical symbols on any one of the nine played lines, so long as the matching symbols were placed from left to right.
They were told that there were two exceptions to this left-to-right rule: 1 the violin symbol which was a scatter symbol, and 2 the stereo triplet that occurred on reels 3, 4 and 5.
Participants who began with the stop button were shown how to use the stop button and were instructed to use it on every spin in that session.
Skin conductance electrodes were attached at this point, and participants were instructed to keep their left hand still to the best of their ability while playing the slot machine.
Following this instruction period, participants played the first block of 250 spins with or without the stop button, counterbalanced.
A pop-up message occurred at the end of 250 spins, whereupon participants were instructed that they would now complete a short questionnaire i.
The in-game GEQ was completed once more upon completion of the second block of 250 spins.
Participants were detached from the skin conductance apparatus and then completed the post-game questionnaire battery including the GCRS and erroneous cognitions items specific to the near-miss and the stop button.
For purposes unrelated to the current study, participants also completed the DASS-21.
Of the 132 participants who had completed the PGSI, there were 26 non-problem gamblers, continue reading low-risk gamblers score of 1—4 on the PGSI19 moderate-risk gamblers and 24 Problem Gamblers scoring 8 or greater on the PGSI.
Seven participants withdrew from the study prior to play free casino games slot all of the measures leaving a sample of 125 participants for the subjective measures.
Based on these frequencies, a small but meaningful percentage of players endorse these beliefs 16% endorsed the belief that near-misses reflected skill at slots, and just over 11% believed that near-misses were a harbinger of upcoming wins.
Each item was also significantly related to the subscales of the GRCS as shown in Table.
By contrast, a concerning total of 15 participants 12% agreed with this statement, and 2 1.
We also calculated a composite score based on the items from Ladouceur and Sévignydesigned to assess whether participants held erroneous beliefs about the stop button.
Composite scores were also significantly correlated with the illusion of control, predictive control and interpretive bias scales of the GRCS See Table.
Further, both the single item and the composite items were unrelated to gambling expectancies, and only weakly related to cognitions about the inability to stop gambling.
Thirty-four of the 125 respondents preferred the game with the stop button feature.
As the question format was dichotomous, the remaining 91 respondents preferred the game without the stop button.
In-Game Physiological Measures: Data Reduction and Analysis Strategy Of the 132 participants, seven dropped out prior to completing both slot machine tasks.
In analyzing our physiological measures, we partitioned our analysis in two ways.
Firstly, we performed separate repeated measures analyses of variance ANOVAs for skin conductance SCRsforce, and post-reinforcement pauses.
The repeated factors were outcome type losses, gramophone near-misses, LDWs, small regular wins, gramophone wins and stereo triplet wins and the stereo triplet near-misses and button use stop button, no stop button.
We then conducted a more restricted version of the analyses above in which the outcomes measured were limited to the three types of losing outcomes that result in no credit gains.
We made an a priori decision not to look at gambling status effects because no effects of gambling status had been shown to influence these in-game measures in our previous studies.
For all repeated measures analyses effect sizes were measured using partial eta squared arcade slot free play as η 2.
A significant effect of outcome was also observed, F 1.
As shown in Fig.
The lack of interaction indicates that using the button did not preferentially inflate the SCRs on any particular outcome.
Left panel Average skin conductance response magnitudes following winning and losing outcomes.
Right panel Average skin conductance responses for the full loss outcomes credit gains of zero in the no stop button and stop button conditions.
Error bars ±1 More info As can be seen in the left panel of Fig.
Among these outcomes the only statistical difference was that inexplicably gramophone near-misses had significantly smaller SCRs than losses—none of the other contrasts were significant.
There was also a significant outcome by button use interaction, F 1.
Average SCRs following losing outcomes are displayed in the right panel of Fig.
The main effect of outcome is attributable to the greater magnitude of SCRs for stereo triplet near-misses, compared to gramophone near-misses or regular losses.
For the no stop button condition, there was a large main effect of outcome F 1.
Similarly, in the stop button condition the effect of outcome was also something europlay casino instant play goes significant, F 1.
As can be seen in the right panel of Fig.
A main effect of outcome was also observed, F 3.
Crucially, as shown in the left panel of Fig.

Error bars ±1 SE The restricted analysis of PRPs for the three types of full losses losses, gramophone near-misses, stereo near-missesshowed that the main effects of both button use and outcome were not significant.
Crucially however, there was a significant button use by outcome interaction, F 1.
Simple effect analyses revealed that there was a main effect of outcome only in the stop button condition, F 1.
As shown in the right panel of Fig.
In the present study, players played two separate games on a slot machine simulator: one involving the use of the stop button, and the other without the use of a stop button.
We sought to assess whether two distinct structural slot machine features, the stop button and near-miss outcomes, would perpetuate a unique set of erroneous cognitions and amplified emotional responses related to the presence of such erroneous cognitions.
Perhaps not surprisingly, the use of the stop button was affiliated with erroneous cognitions related to skill and the ability to influence the outcomes of the game.
Indeed, erroneous cognitions related to the stop button were specifically correlated with the illusion of control and predictive control subcomponents of the Gambling Related Cognitions Scale.
When asked about the role of the stop button during play, 13.
This is a troubling percentage of players when one considers that signage in Ontario casinos explicitly indicates that the stop button does not influence the outcomes on the machines.
This relationship supports previous research showing that skill-oriented beliefs in games play machine slot chance are core cognitive processes that shape problem gambling behaviour Griffiths ; Myrseth et al.
The use of the stop button impacted how players actually played these games.
It impacted how players reacted to both winning and losing outcomes of the games.
Our analysis of the force which players initiated spins indicates that for all outcomes players used more force to initiate the next spin when using the stop button.
They also showed larger SCRs for all outcomes except for the stereo near-misses when using the stop button.
If players were merely using the stop button to reveal the outcome faster, there is no reason to assume they would pull the stop button especially hard.
If, however, players were attempting to stop the reels at a given outcome, then they would likely pull hard to get the reels to stop spinning at a winning combination.
The arousal and effort used to stop reels at a winning combination could then bleed over into the initiation of the next spin, causing players to initiate spins with greater force in the stop button condition than the no-stop button condition.
Thus the finding of greater SCRs and greater force in the stop button condition may constitute in-game evidence of the erroneous cognitions we saw using the post-game questionnaires where at least some gamblers thought that using the stop button was related to skill at slots.
Although in our simulator and in actual slots gamesstop buttons merely reveal the outcome faster, our force results suggest that play machine slot feel they can impact the outcomes of the games by pulling at just the right time.
As such our force and SCR results may actually reflect the illusion of control during play.
Another notable aspect of our force measures is that unlike SCRs, force pulls appeared to be quite sensitive to the amount of credits gained.
Whereas the losses, LDWs and small wins, and even the large gramophone win all led to roughly equivalent SCR responses see the first five outcomes listed in the left panel of Fig.
This finding may be quite important when one considers ecological validity.
With SCRs, participants have to be repeatedly told not to move their non-dominant hand lest they mar the SCR recordings.
The visual presence of the electrodes on their fingers, the wires connecting the electrodes, along with such movement constraints, may prevent players from becoming as absorbed as they normally would in the slots games.
Of course, further validation is needed to confirm the sensitivity of the force measure to appetitive and frustrative reactions.
All three in-game measures converged to play machine slot that players erroneously interpret near-miss outcomes as conveying something very different than regular losses.
When stereo triplet near-misses were compared to losses, they triggered significantly greater SCRs in both the stop button and no-stop button condition suggesting that players reacted to these outcomes with more frustration than regular losses.
This interpretation was bolstered by our measures of force to initiate the next spin.
In both the stop button and no-stop button condition, players used greater force to initiate the next spin following near-misses than following regular losses.
In the no-stop button condition PRPs for the highly salient stereo near-misses were equivalent to other losing outcomes and far shorter than any winning outcome.
This finding is consistent with our previous work Dixon et al.
In contrast to play without the stop button, significant PRP differences between stereo near-misses and regular losses did occur when players used the stop button.
It is important to note that in both button conditions the PRP was measured in the same way from the time of the last reel stopping and the initiation of the next spin.
Although one might suspect that an action immediately prior to this measurement i.
As shown in Fig.
As such our findings are unlikely due to the stop button interfering with PRPs in a general sense.
Although the near-misses in the stop button were significantly longer than other types of full losses, they were still more similar to these losses than to wins i.
Thus, the explanation that players are misinterpreting near-misses as wins does not seem to translate to our findings.
Rather, it may be that the small increase in length of the PRP for stereo near-misses when players use the stop button is attributable to a brief skill-related evaluation period.
This may also account for the pattern of SCRs shown in Fig.
While SCRs were higher in the stop button compared to the no stop button condition for losses, gramophone near-misses, LDWs, small wins, gramophone wins and stereo triplet wins, they were equivalent for stereo triplet near-misses.
It may be that skill-related mentations may have curtailed the arousal due to frustration in this key condition.
Overall our interpretation of the SCR, PRP and force findings is that at least for some players the stop button is encouraging a perception of skill not otherwise present in the games without the stop button.
As such, it is possible that players are more attuned to perceiving the near-misses as a form of performance feedback.
If they perceive themselves to be personally responsible for this near-miss, one might expect a longer pause to evaluate their proximity to this desired win.
The latter liking component would of course be indexed to the very long PRPs, high SCRs and large force associated with the exciting stereo triplet wins.
Consistent with Dixon et al.
For all measures in the current study, the horizontal triplet wins led to an enhanced response over and above the gramophone win, even though both win types were equated in terms of value.
The finding that players showed significantly larger SCRs, force and PRPs following the stereo horizontal triplets compared to the gramophone wins shows that slot machine game designers can sensitize players to certain symbols over others.
While near-miss effects have often been my iphone on poker play i 888 can in single-line games, this study replicates the findings of Dixon et al.
The slot machine simulator was played on an ordinary laptop computer, which lacks many of the cues and capabilities of an actual slot machine.
Additionally, our measures involving skin conductance where participants had electrodes attached to their fingers of their non-dominant hand, and were instructed not to move said hand, could affect how absorbed players become in slots play.
Such playing conditions are novel and unnatural for any slot machine player.
Also the rather standard limitation for studies of this type, namely that players were not using play machine slot own money certainly applies here.
It may be that the robust effects shown would be even more prominent in more naturalistic settings.
The current study makes two novel contributions: First we move beyond the classic near-miss effects that have been demonstrated in simplistic, three-reel slot machines.
Here we show that near-misses can dramatically affect player frustration and arousal even despite the complexity of the winning and losing symbol alignments in multi-line games.
This extension is important given that multiline games appear to be the games of choice for seasoned gamblers Livingstone et al.

In general, players elicit greater levels of arousal for a vast majority of the outcomes, and a more amplified frustration response to winning and losing outcomes.
