As on modern games with mechanical reels, results are determined by a random number generator.
Nothing is ever quite that simple, and there are important things to know before you play video or online slots: You just slide your money into the bill validator, choose how many paylines to play and how many coins to wager per line, and hit the button to spin the video reels. Like slots with mechanical reels, video slots and online slots are easy to play. Online, of course, all games are on video. Slot machines have their roots in three-reel mechanical games, but the large majority of slots in modern brick-and-mortar casinos are played on video screens.
