Casino machines, often referred to as slot machines or poker machines, are popular gaming devices found in casinos. They operate by inserting money or a token, pulling a lever or pressing a button, and waiting for the reels to spin and stop. If the symbols align in a winning combination, the player receives a payout. Some machines also feature bonus rounds and progressive jackpots, which can lead to larger winnings.
