Slot machine - Wikipedia, the free encyclopedia |
 | | Traditional slot machines are coin-operated machines with three or more reels, which spin when a lever on the side of the machine is pulled. |
 | | The winning patterns on slot machines, the amounts they pay, and the frequency at which they appear are carefully selected to yield a certain percentage of the cost of play to the "house" (the operator of the slot machine), while returning the rest to the player during play. |
 | | Each slot machine in the group contributes a small amount to this progressive jackpot, which is awarded to a player who gets (for example) a royal flush on a video poker machine, or a specific combination of symbols on a regular or 9 line slot machine. |
