Unlike the Sittman and Pitt invention, Charles Fey’s slot machines allowed payouts with the press of a button and could hold multiple symbols. His design, which featured a reel window with three aligned liberty bells, was a hit. The slot machine evolved from there, eventually offering more pay lines and special features.
Today’s slot machines are powered by microprocessors that allow manufacturers to weight particular symbols. This makes it appear that a winning symbol has a greater chance of appearing on a given spin than is actually the case. The increased hold has been criticized as decreasing the average time spent on machines, though researchers have found that players cannot feel the effects of changes to hold.
In addition to establishing loss limits, it’s important for slot players to understand the math behind the game. The amount that a player wins is determined by the number of symbols that line up on a pay line. In a “Buy A Line” machine, the number of tokens played determines how many pay lines are activated; playing all pay lines results in the highest possible win. A random number generator inside the machine selects the odds of a win, and a winner is announced when a winning combination appears on one or more of the pay lines.
