Misinterpreting ‘winning’ in multiline slot machine games

On multiline slot machines, ‘wins’ often amount to less than the spin wager, resulting in a monetary loss to the gambler. Nevertheless, these losses disguised as wins (LDWs) are accompanied by potentially reinforcing audiovisual feedback. A concern for gambling behaviour is whether or not players categorize LDWs as wins or losses, as miscategorization could effectively increase the reinforcement rate of these games. The purpose of this study was to evaluate whether novice gamblers psychologically miscategorize LDWs. Forty-seven novices (undergraduate students) played 200 spins on an actual slot machine with credits, then estimated how often they won. It was found that the more LDWs players were exposed to, the higher their win estimates. In a subsequent ‘think out loud’ playing session, the majority of novices also verbally miscategorized LDWs as wins. We conclude that LDWs could increase the reinforcement rate of these games, despite not increasing the payout to the gambler.     

Gamblers can discriminate ‘tight’ from ‘loose’ electronic gambling machines

All slot machines make money over time, but the payouts to the players can differ. ‘Loose’ machines pay out more than ‘tight’ machines. Gamblers (n = 1402) at Ontario slots venues were assessed using the Problem Gambling Severity Index. Their beliefs about slots were polled using the Informational Biases Scale. Problem gamblers were more likely than non-problem and at-risk gamblers to endorse the belief that ‘some slot machines keep me from winning because they are programmed to produce fewer wins than normal’. We then showed that after extensive play (60 hours), 9 out of 10 gamblers were able to correctly discriminate a ‘loose’ machine (98% payback) from a ‘tight’ machine (85% payback). Problem gamblers' assertions that there are ‘loose’ and ‘tight’ machines demonstrate a belief rooted in reality. The ability to distinguish ‘loose’ from ‘tight’ machines may be interpreted as a skill by players. Such skill, when overestimated, may lead to erroneous cognitions.     

An empirical real-world study of losses disguised as wins in electronic gaming machines

Losses disguised as wins (LDWs) appear to reinforce gambling persistence. However, little research has examined this phenomenon with real gamblers in natural gambling settings. We aimed to examine the relationship between within-session outcome size and subsequent gambling persistence. Account-based gambling data of individuals playing LDW games over a randomly selected day (2,035,339 bets made by 8636 individuals) was examined. We used a logistic mixed effects model to examine the relationship between the outcome of the previous bet (loss, LDW and real wins) and the odds of continuing betting in a game session. The odds of continuing betting in a game session were positively associated with the outcome of the previous bet. Compared to LDWs, losses lowered the odds of continuing a game session. In contrast, real wins implied greater odds of continuing a game session compared to LDWs. It is concluded that LDWs increase the likelihood of continuing betting compared to losses, but decrease the likelihood of continuing to gamble compared to real wins. As LDWs increase the number of bets made within a gambling session, and hence within-session gambling persistence, LDWs may potentially play an etiological role in the development of gambling problems over time.     

An Empirical Investigation of Theoretical Loss and Gambling Intensity

Many recent studies of internet gambling—particularly those that have analysed behavioural tracking data—have used variables such ‘bet size’ and ‘number of games played’ as proxy measures for ‘gambling intensity’. In this paper it is argued that the most stable and reliable measure for ‘gambling intensity’ is the ‘theoretical loss’ (a product of total bet size and house advantage). In the long run, the theoretical loss corresponds with the Gross Gaming Revenue generated by commercial gaming operators. For shorter periods of time, theoretical loss is the most stable measure of gambling intensity as it is not distorted by gamblers’ occasional wins. Even for single bets, the theoretical loss reflects the amount a player is willing to risk. Using behavioural tracking data of 100,000 players who played online casino, lottery and/or poker games, this paper also demonstrates that bet size does not equate to or explain theoretical loss as it does not take into account the house advantage. This lack of accuracy is shown to be even more pronounced for gamblers who play a variety of games.     

Event frequency,excitement and desire to gamble,among pathological gamblers

In this study we compared gambling behaviour of 15 pathological gamblers (PG) and 15 non-problem gamblers (NPG) on two conditions of a commercially available slot machine. One condition used a commercially available two-second event frequency (games per minute), while the other condition used an experimental three-second event frequency. The payback percentage (wins relative to losses) and reward frequency (wins over number of games played) varied randomly across conditions. The results showed that PG had significantly higher measures than NPG on time spent gambling, excitement level and desire to play again in the two-second condition. In the three-second condition there were no differences in excitement level and desire to play again. The number of PG playing the maximum time (60 minutes) was reduced in the three-second version, and reward frequency contributed to reduction in time spent gambling. The results may have implications for understanding behavioural mechanisms of pathological gambling among slot machine players.     

Losses disguised as wins in multiline slots: using an educational animation to reduce erroneous win overestimates

Slot machines are available in several countries, with multiline games growing in popularity. Interestingly, many audiovisually reinforced small ‘wins’ in multiline games are in fact monetary losses – outcomes referred to as losses disguised as wins (LDWs). Research suggests that LDWs cause players to overestimate how many times they remember actually winning during a playing session. The study sought to replicate this finding and see if a short educational animation about LDWs could significantly reduce this LDW-triggered win overestimation effect. It employed a mixed design, with animation viewed (LDW, control) as the between-subjects factor, and game played (200 spins on a few LDW or many LDW game; game order counterbalanced) as the within-subjects factor. Fifty-four novice participants estimated how many times they won more than they wagered in each game. In the control animation group, the study replicated the LDW-triggered win overestimation effect for participants playing the many LDW game. Crucially, win overestimates were significantly reduced in this many LDW game for players exposed to the LDW animation. The study concludes that LDWs can lead novice gamblers to remember winning more often than they actually do during a playing session, but educating participants about LDWs can reduce these erroneous win overestimates.     

Differences in motivational dimensions across gambling frequency,game choice and medium of play in the United Kingdom

Motivations to gamble in the United Kingdom were examined in relation to gambling preferences and behaviour (gambling frequency, game choice, medium of play). A factor analysis delineated six motivational dimensions for gambling as a leisure activity: socialization through learning, escape, peripheral activity, fun/challenge, socialization through competition, and to win money. The motivational dimensions differed significantly for various gambling frequencies and across choice of games, though not across different media of play. More frequent gamblers chose to gamble for escape and/or fun/challenge purposes, while less frequent gamblers chose to gamble for socialization through learning and peripheral activities. Certain gambling motivations significantly affected decisions to play lottery, roulette, poker, betting and slots, but motivations were not significantly different from each other for bingo, blackjack, fixed-odds betting terminals and football pools. The research extends current knowledge of motivations in the UK and recreational gamblers, introducing a new motivational factor – activities indirectly related to gambling – and emphasizing the relationship between gambling motivations and behaviours. Knowledge of motivations assists casino operators in creating effective marketing strategies and aids lawmakers in better understanding the gambling objectives of their citizenry. These motivational dimensions also serve as a baseline against which problematic motivations can be compared.     

Dark Flow,Depression and Multiline Slot Machine Play

Multiline slot machines allow for a unique outcome type referred to as a loss disguised as a win (LDW). An LDW occurs when a player gains credits on a spin, but fewer credits than their original wager (e.g. 15-cent gain on a 20-cent wager). These outcomes alter the gambler’s play experience by providing frequent, albeit smaller, credit gains throughout a playing session that are in fact net losses. Despite this negative overall value, research has shown that players physiologically respond to LDWs as if they are wins, not losses. These outcomes also create a “smoother” experience for the player that seems to promote a highly absorbing, flow-like state that we have called “dark flow”. Past research has indicated that there may be a relationship between problem gambling status and dark flow, as well as between dark flow, depression, and gambling expectancies. In this study, we sought to further understand these relationships, while examining the influence of LDWs on game preference in the context of single versus multiline slots play. We used a realistic slot machine simulator equipped with a force transducer to measure how hard players pressed the spin button following different outcomes. This measure of arousal showed that LDWs were treated similarly to small wins. Participants overwhelmingly preferred the multiline game and experienced more positive affect while playing it, compared to the single-line game. Problem gambling severity index scores were related to dark flow in both games, but this relationship was stronger for the multiline game. Additionally, depression symptomatology and dark flow were strongly correlated in the multiline game, with significant relationships between depression and gambling expectancy, and gambling expectancy and dark flow ratings also emerging.     

Gambling attitudes and beliefs associated with problem gambling: the cohort effect of Baby Boomers

Recreational and problem gamblers alike hold beliefs about gambling that are dysfunctional. These dysfunctional beliefs have been theorized to play a role in problem gambling behaviour. The current study sought to examine the effects of gambling attitudes and beliefs on problem gambling behaviour across three cohorts. A sample of 308 participants consisted of 101 individuals from Generation X, 139 from the Baby Boom cohort and 68 from the Silent Generation. Hierarchical multiple regressions showed that for Baby Boomers, higher scores on scales measuring beliefs about luck and illusions of control were associated with higher scores on measures of problem gambling than for the Silent Generation. Generation X’s higher scores on luck scales were associated with higher scores in problem gambling than the Baby Boom cohort. Attitudes associated with problem gambling did not differ among cohorts. These results suggest that while cohorts may not differ in types or levels of distorted beliefs, they differ in how such distortions relate to problem gambling. Future research should focus on determining whether such cohort effects are indicative of differences within the development and maintenance of problem gambling itself.     

Reduced inhibitory control predicts persistence in laboratory slot machine gambling

Impairments in inhibitory control characterize a range of addictive behaviours including gambling disorder. This study investigated the relationship between a neuropsychological measure of inhibitory control and behaviour on a simulated slot machine that included a measure of gambling persistence, in a non-clinical sample of regular gamblers. Regular gamblers (n = 75) performed a laboratory slot machine task for 30 trials where they could win real money, followed by a persistence phase under extinction (i.e. without wins). Participants also completed a stop-signal task, along with measures of gambling-related cognitions, social desirability, and symptoms of disordered gambling. In hierarchical regression models, reduced inhibitory control was found to predict greater persistence and a higher subjective desire to play again after both wins and near-misses (i.e. unsuccessful outcomes close to the jackpot). These data illustrate the impact of low inhibitory control on relevant behavioural tendencies in a group of regular gamblers. Our results help elucidate a cognitive process that may contribute to problem gambling, with implications for screening and treatment.     

A review of Australian classification practices for commercial video games featuring simulated gambling

This paper reviews Australian classification practices for commercial video games that contain simulated gambling. In the last decade, over 100 video games featuring gambling simulations have been classified as suitable for commercial sale to youth in Australia, with 69 of these video games rated ‘PG’ for Parental Guidance Recommended (i.e. suitable for ages 8+years) and the remaining 33 rated ‘G’ for General (i.e. suitable for all ages). A review of the literature suggests that consumer advice and warnings related to video game material are often inconsistent and/or not adequately provided. A public health approach suggests that the presence of gambling content in video games may present risks to younger players unfamiliar with how gambling operates. It is argued that there is a need for further academic debate on social responsibility issues of early childhood and adolescent exposure to, and involvement in, simulated gambling activities available in interactive gaming technologies.     

Brief Communication: “If You Do Not Gamble, Check This Box”: Perceptions of Gambling Behaviors

Most adults in the U.S. have participated in one or more gambling activities. However, many people engage in gambling activities without considering themselves as gamblers. Four hundred and forty-nine university students returned surveys about their participation in gambling activities. After completing a questionnaire recording the style and frequency of gambling participated in, respondents were asked to indicate whether or not they gambled. Results indicated that gamblers participated in twice as many forms of gambling activities as those who classified themselves as non-gamblers. Scratch tickets and lottery tickets were not generally considered gambling unless purchased frequently. Casino visits, bingo, dog races, football pools, golf matches, local poker games, and other card games were more likely to be viewed as gambling, especially when engaged in frequently. Subjects who had gambled on at least one occasion with bookies, dice games, video poker in a bar, dog or cock fights, or off track betting almost always identified themselves as gamblers. It is recommended that further research be conducted to clarify the gambling activities, and frequency of those activities, that influence a person's perceptions of gambling.     

Exploring psychological need satisfaction from gambling participation and the moderating influence of game preferences

ABSTRACT

Psychological needs are satisfied through leisure participation, which in turn influences subjective well-being. The present study explored the psychological needs reported to be satisfied through gambling participation and examined associations between need satisfaction, game preferences and subjective well-being. A heterogeneous, self-selected sample of 1446 participants was recruited, through the Internet gambling provider Kindred Group Plc, for an online questionnaire survey. Five psychological need dimensions of gambling were identified, using exploratory and confirmatory factor analyses on calibration and validation samples, respectively: mastery, detachment, self-affirmation, risk and excitement, and affiliation. Challenge and mastery need satisfaction was higher for poker than for sports betting, horse racing, slots or casino table games; both self-affirmation and affiliation were also higher for poker than for sports betting and slots. By comparison, detachment was higher for slots than for sports gambling. While there were no significant variations in stress levels between the different forms of gambling, happiness ratings were lower for slots compared with sports betting and poker. This study provides insight into how distinctive patterns of play may satisfy different psychological needs and provides preliminary insights into how gambling patterns may prove adaptive or maladaptive as leisure choices.     

Gambling participation in the U.S.--results from a national survey

Demographic patterns of gambling participation in the U.S. were examined. A national telephone survey was conducted with 2,630 representative U.S. residents aged 18 or older. The sample as weighted for analysis was 48% male, 12% black, and 11% Hispanic. Respondents were questioned on 15 types of gambling: how often they played and how much they won or lost. Eighty-two percent gambled in the past year. Lottery was the most commonly played game, while casino gambling accounted for the largest extent of gambling involvement. Men and women were equally likely to gamble in the past year, but men gambled more frequently and had larger wins and losses, particularly on sports betting and games of skill. Blacks were less likely to have gambled in the past year, but blacks who gambled did so more heavily than other racial groups. Blacks and Hispanics were more likely than average to be pathological gamblers. The rate of past year gambling declined with age, but extent of gambling involvement among gamblers did not vary with age. Rates of participation in most forms of gambling increased with socioeconomic status, but higher socioeconomic status gamblers had lower rates of pathological gambling, and lower extent of gambling involvement, particularly for lottery. New Englanders gambled more heavily than other Americans. Comparison with past studies showed an increase in overall gambling participation in the U.S., and large increases in rates of participation in lottery and casino gambling.     

Development of the Drake Beliefs about Chance Inventory

The present research describes the development and validation of a cognitive assessment instrument, the Drake Beliefs about Chance (DBC) inventory, designed to determine and quantify erroneous beliefs about games of chance. Principal components analyses showed that the DBC assesses two primary dimensions, Illusion of Control and Superstition. Correlation analyses showed that scores on these two dimensions are related to higher frequency of gambling behaviors in both adults from the general population and clients from gambling treatment centers. Of the two sets of erroneous beliefs, Illusion of Control was a better predictor of gambling than Superstition. This investigation provides additional evidence that participants in games of chance such as casino gamblers possess certain classes of erroneous beliefs regarding the games they play.     

Superstitious Beliefs in Gambling Among Problem and Non-Problem Gamblers: Preliminary Data

Superstitious beliefs, defined as a strong conviction based on the erroneous perception of a cause-effect association between two independent events, are considered to play an instrumental role in the maintenance of gambling behaviour. In this preliminary study, responses to eight items assessing superstitious beliefs were compared among 56 electronic gaming machine (EGM) problem gamblers, 22 non-problem EGM and 23 non-EGM non-problem gamblers. Results suggested that problem gamblers endorsed more superstitious beliefs than non-problem gamblers and that such beliefs were correlated with gambling intensity. Further research is required to determine if superstitious beliefs represent a vulnerability factor for the development of problem gambling or emerge as a consequence of involvement in gambling.     

Problem gambling in poker: money,rationality and control in a skill-based social game

The article explores problem gambling in poker. The distinctions between chance and skill and between bank games and social games are applied to demonstrate how poker is structurally different from most other gambling games. Bank games are organised around a central actor such as the house, the casino or the bookmaker. In social games, players compete against each other on equal statistical footing. Poker is a skill-based social game where players with superior skills may be expected to win even in the long run. Fourteen poker playing problem gamblers were recruited through a treatment program and 15 professional and recreational poker players were recruited through snowball sampling (N = 29). Through qualitative interviews, the paper shows that the particular structural composition of poker has implications for the ways problem gambling arises in poker players. It is argued that poker challenges existing theoretical conceptions about problem gambling relating to money, rationality and control.     

Near Wins Prolong Gambling on a Video Lottery Terminal

The purpose of the present study was to evaluate whether near wins can prolong gambling activity on a video lottery terminal. In a three-reel game, near wins were operationally defined as two identical symbols followed by a third different symbol. Players in an experimental condition were exposed to 27% near wins in a series of continuous losses, whereas players in a control group were exposed to none. Participants played as long as they wished, and received real money for their wins. The results showed that players in the near win condition played 33% more games than did the control group. The results of this study suggest that near wins can be added to the list of factors that may motivate people to gamble despite the probability of monetary loss.     

Real Limits in the Virtual World: Self-Limiting Behavior of Internet Gamblers

The recent expansion of Internet gambling has stimulated debate, policy, and research on this relatively new phenomenon and its potential consequences. The current study focuses on bettors experiencing problems by sampling Internet gamblers who imposed limits on the amount they were allowed to deposit to a betting site. We analyzed the betting transactions over 18 months of all gamblers who subscribed to an online betting site in February, 2005 (N = 47,134), 567 of whom utilized the site’s self-limit feature. Self-limiting gamblers played a wider variety of games and placed more bets than others prior to imposing limits. After imposing limits, self-limiters reduced their activity, but did not reduce the amount they wagered per bet. Time spent gambling, not just money spent, appears to be an important indicator of gambling problems. Self-limit programs appear to be promising options for Internet gamblers at-risk for gambling problems.
