Traditionally, slot machines used revolving mechanical reels to display and determine results. But microprocessors have replaced the older technology and made it possible for manufacturers to create a wider variety of games with different payouts and bonus features.

Players can choose to bet on any number of paylines and may win if the symbols line up in horizontal, vertical, diagonal or zigzag patterns.

When playing slots, it’s important to understand how the game works and what your chances of winning are.
