Unlike their simpler, mechanical predecessors, today’s slot machines are all about flashing lights and digital displays. However, their basic premise remains the same. A spinning reel is loaded with symbols that reveal themselves in a random order, thanks to an electronic program called a random number generator. When you push the spin button, a sequence of numbers is recorded by the RNG and compared with an internal sequence table. The computer then matches the resulting three-number combination to a particular symbol on the reel.

The result is that some machines pay out more often than others, and the amount you win is based on how many lines you activate, the type of symbols and their value, and whether the bonus game is active. This makes understanding a slot’s payout structure essential to making the best decisions about which machine to play and how much to bet.
