A slot is a location on the surface of a disk or other storage medium. It can also refer to a position in a computer or other device that holds memory. In computer systems, a slot (also called an expansion slot) is a set of pinholes in the motherboard on which an add-on card can be fitted to provide additional capabilities. Most desktop computers come with a number of expansion slots, which allow for the addition of various hardware capabilities.
Psychologists Robert Breen and Marc Zimmerman have found that players of video slots reach a debilitating level of involvement with gambling three times as fast as those who play traditional casino games. They do so even if they have previously engaged in other forms of gambling without problem.
Despite these findings, the popularity of video slot machines continues to rise. The psychological mechanisms underlying this phenomenon are unclear. One possibility is that near-miss events encourage continued play by providing a sense of hope for future winnings. The present experiment tested this hypothesis by manipulating the frequency of near misses on a slot machine simulator. Participants were then placed on an extinction condition that removed both wins and near misses, and self-reports of willingness to continue play in the future were evaluated. Results suggest that near-miss events do in fact reinforce continued play, a finding that has important implications for the design of slot machines and other games of chance.
When choosing which machine to play, pick the ones you like the most. While luck plays a big part in how much you win, enjoying the machine increases your chances of success. Whether you prefer the simplicity of a single pay line or the more elaborate bonus features, it is important to find a machine that fits your taste.
