The random number generator, also abbreviated to RNG, is the algorithm that determines the symbols that appear on a slot machine. It is a key element in all slot games and cannot be tampered with by players or anyone outside the slot industry. This is to protect players and maintain fairness in the games and the industry.

The RNG is a complex mathematical system that uses variables to create results based on specific time stamps that are several decimal places deep. It can therefore be impossible to predict the outcome of any individual spin. This makes slot games completely fair for all players and ensures that there is no advantage or disadvantage based on the time of day when a player plays a slot.

Winning a slot game depends on the type of combination that lands on the payline, which is a predefined straight or zig-zagged line that extends horizontally across the reels. The different symbols can offer varying payouts, depending on their appearance on the payline and what other symbols are involved. Cherries, for example, are common on classic slots and typically offer a small payout. Single and double bars may offer higher payouts, while triple bar symbols offer the highest payouts of all.

The paytable of a slot is located within the main gaming screen and explains all of the symbols and their payout odds. It is worth studying this thoroughly before you start playing, as it can help you to work out the probability of winning a particular slot game and determine how much your wins will be.
