A Slot is a gambling machine that pays out based on the combination of symbols on a reel. It is one of the most popular games in casinos and has a wide variety of payoffs.
The History of Slots
Slot machines were once a rarity in American casinos, but their popularity has grown exponentially. Today, they account for up to 85 percent of gaming profits.
How Slots Work
Modern slots are controlled by a computer inside the machine that spins the reels and determines the theoretical payout percentage of each symbol. High tech stepper motors are used to operate the reels, allowing them to come to rest at a precise point in rotation as determined by the MPU control board.
Cheaters and Countermeasures
Before modern technology, cheating was a common practice on slot machines. In the 1960s and ’70s, scam artists would place ordinary magnets on the reels and make them spin freely instead of stopping when they aligned in a winning combination.
Using a Steppermotor
Today’s modern slot machines use high-tech stepper motors that are similar to the ones that operate the reels in spacecraft. These motors are extremely powerful and are able to stop at a precise, predetermined point in the rotation of each individual reel symbol. This allows the computer to control the game and ensure that only coins are paid out for matching combinations of symbols.
