In slot machines, the reels are vertical sections that spin when the machine is activated by a lever or button. Depending on the game, players can win credits by lining up matching symbols on pay lines that run horizontally, vertically or diagonally across the reels. The symbols vary according to the game’s theme. Modern casinos typically place slots in areas based on denomination, style and brand name, and many have a help or INFO button that will explain payouts, symbols, bonus games and other features. In some cases, the methodology used by a particular machine is spelled out on the glass above the machine.
