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.
