Historically, slot machines have used mechanical reels to display symbols and pay out credits when the correct combinations are made. During the 1980s, manufacturers introduced electronics to control these machines. The earliest digital slot machines were programmed to weight particular symbols, meaning that they would appear more often on the pay line than other symbols. This reduced the overall odds of hitting a losing combination.

In modern online slot games, the reels are controlled by computer software. This makes it possible to create a wide variety of themes and variations of the classic games. Some slot machines are themed after movies or television shows, while others are designed to look like old-fashioned fruit machines or other familiar objects. The software can even incorporate special effects, such as sound effects and animations, into the game play.
