In a slot machine, a player inserts cash or, in “ticket-in, ticket-out” machines, a paper ticket with a barcode into a designated slot. The machine then activates reels that spin and stop to rearrange symbols. When a winning combination is achieved, the machine pays out credits according to its pay table. Symbols vary by game, but classics include fruits, bells, and stylized lucky sevens. Each machine is programmed to weight certain symbols more heavily than others. This is why one symbol may appear only once on a reel displayed to the player, while it may actually occupy several stops on the multiple-reel physical machine.
