# What is a Slot Machine?

A Slot machine is a gambling machine that uses a random number generator to determine the outcome of spins. While the original slot machines had large metal hoops as reels, today’s versions are powered by computers. Random numbers are determined by a mathematical formula, rather than a physical process. In addition, a Slot machine’s reels are usually images on a video screen. If you find a Slot machine with a “wiggling” reel, this may be an indication that it needs repairs.

A computer is used to produce the random number sequence. The computer divides large numbers by a standard number, resulting in a three-number sequence. This process is done automatically. The computer then uses its internal sequence table to determine the next number in the sequence. If the quotients are different, then the game has been won. Hence, a slot machine cannot predict the next number. Instead, it cannot win the jackpot.

The payback percentage of a slot machine is calculated according to long-term mathematical expectations. If ten different symbols appear on a payline, there is a 1/10 chance of each of them appearing. This result means that a machine can have a win or a loss on more than one payline. If a player wins on more than one payline, the total winnings will be shown as net winners, even though the player has lost ten cents.
