The core mechanism that ensures fairness and unpredictability in slot games is a random number generator (RNG), which generates an unbiased sequence of numbers for each spin, thereby guaranteeing that each outcome stands alone, independent of previous or accompanying events. This ensures that slots are games of chance and that any strategy based on previous outcomes is ineffective.

As the number of paylines and bonus features in slot games has increased, many players find it difficult to keep track of them all at once. To help with this, slot developers include information tables known as pay tables, which display the regular paying symbols in a game and their payout values. They also provide details on any bonus features and how to trigger them.

The pay table is also where you can find important information about the volatility of a slot game, which is determined by highly diversified spin outcomes. The higher the volatility, the more risky a slot game is. In general, you want to pick a slot with low volatility (less risk, more consistency), but this can be difficult to determine without playing the game for some time.
