This experiment used motivational instructions to test whether experienced slot machine players are able to manipulate the frequency of winning outcomes and the time taken to deplete funds while playing a popular slot machine game. Twenty-four participants played in four conditions intended to motivate them to play the game as they normally do, to deplete funds quickly, to get a long losing streak, and to avoid getting a bonus round. Compared to how they normally play, participants significantly reduced the number of bought paylines when trying to get losing streaks or avoid bonus rounds. They also wagered significantly more credits per line when trying to deplete their funds quickly. This experiment shows that experienced slots gamblers have an implicit understanding of reinforcement rate and time on device, and that they are able to manipulate these game outputs at will by adjusting the number of paylines they buy and how many credits they choose to wager. When playing normally, they try to maximize reinforcement rate by purchasing the opportunity to win on many paylines. Player control over reinforcement rate and time on device does not alter payback percentage so there is no monetary advantage to manipulating these game outputs.
