During the late 1980s, when slot manufacturers began to incorporate electronics into their machines, they also programmed them to weight certain symbols. This caused the odds of a losing symbol appearing on the payline to be disproportionate to its actual frequency on the physical reels. Because of this, many old-time casino players adopted strategies such as moving on to another machine after a short period of play or after making some large payouts (under the assumption that the machine would “tighten up” and become more likely to hit).
Modern slot machines use random number generators to determine the outcome of each spin. The computer chips retain no memory, so each spin is independent of any that came before it. As a result, there is no way to predict which symbols will appear or how frequently they will appear on the paylines.
The pay table in a slot game provides information on the game’s symbols, payouts, prizes, jackpots, and bonus features. It also displays the number of paylines and their configurations. Typically, slot games have multiple paylines that run straight across the reels, in V’s, upside down V’s, zigs and zags, or in other patterns. Some slots also have designated symbols that trigger special bonus features such as free spins, pick-a-prize interactions, or second screen games.
