Charles Fey’s 1907 slot machine was a radical departure from his earlier invention, the Fey-Twine, which required the player to manually pull levers to spin the reels and win. Fey’s invention used a crank and reels to allow players to easily win, and the game became hugely popular. His slots were the first to include symbols other than poker cards—a spade, horseshoe, heart, and liberty bell—and pay out prizes when three aligned liberty bells appeared on the screen.

Despite the popularity of slot machines, some players still believe in outlandish strategies for winning them. For example, some players move on from one machine to another after a certain period of time or after a big payout—under the assumption that the machine is “due” to turn cold. However, these tactics are based on myths, and it’s important to understand that the odds of a machine turning cold or hot are completely random.
