When slot machines were first designed, they had only a few pay lines and a handful of symbols. As the games evolved, they became more complex and a variety of features and bonuses were added. The complexity increased the need for information tables known as pay tables to help players keep track of the different symbols, payouts and jackpots.
When you play a slot game, the odds of winning a jackpot are determined by the probability that a particular symbol will appear on the payline. To determine this, a random number generator (RNG) is used to produce an internal sequence of numbers. Each number is then assigned to one of the symbols on a reel. Since each symbol occupies several stops on a multiple reel, the probabilities of different combinations vary. This is why it is important to test the payout percentage of a slot before spending money.
