Slot machines were invented at the end of the 19th century. They became popular in Las Vegas and in many locations where gambling was allowed. Mechanical machines eventually were superseded by electronic machines that require less maintenance and can be better controlled by the casinos to prevent cheating and to guarantee more consistent profits. Modern slots are programmed with a variety of themes such as storybook fables and even Chinese lucky charm symbols to enhance their general appeal. In the era of the Internet it is now even possible to play bitcoin casino slots.
Slot machines are called "fruit machines" in Britain and "Poker machines" in Australia. The casino gambling machines usually have three or more reels that spin when a button is pushed. Slot machines are also called one-armed bandits because slot machines were originally operated by a lever (arm) on the side of the machine, and because they can leave a gambler penniless.
Some slot machines simulate card games and others have special themes. The most popular slot machines in Las Vegas and Atlantic City casinos are Wheel of Fortune, Fort Knox, Mr. Cashman, Little Lucy, White Ice, Haywire, Ten Times, Jackpot Party, Wild Eights, Triple Cash, Wild Cherry, Double Diamond Haywire, Triple Black Tie, Lucky Four Leaf Clover, Pinball, White Ice, Galileo’s Gold, Blazing Sevens, Double Diamond, Double Double Diamond, Triple Diamond, Ten Times, Tabasco, Bonus Poker, Double Lucky 7's, Sizzling 7's, and Blazing 7's.
