A slot machine game is a gambling game with spinning reels. Those reels have symbols on them, which land randomly after you place a bet and spin the reels. If these symbols line up, you win a prize based on which symbol falls on the “payline”.
These games have been around since the late 19th century, but they have done nothing but grow in popularity since then. They were originally mechanical devices that relied on gears that turned the reels. Modern slot machines use a computer program called a random number generator to determine which land is which symbol.
A random number generator is a computer program that cycles through thousands of numbers per second. When you press the spin button, the program stops wherever it is on. These numbers correspond to stops and symbols on the reels.

Early Slot Machines had easy-to-understand math. You may have 3 reels with 10 symbols on each. Odds of getting the same situs slot particular symbol-10/01. If you want to calculate the odds of getting a certain combination of symbols on the line, you simply multiply 1/10 X 1/10 X 1/10, for a result of 1/1000.
You can then compare the prizes for their symbol layers with the odds of hitting the combination to find out the payback percentage for the machine. If the casino offers 998-1 for bets that have a 1/1000 chance of winning, that casino will have a small edge. Over time, they will show an advantage.
Modern slot games are difficult to count, because the symbols and reels are programmed into the computer. This makes the game more flexible in many ways. They are not limited by roll size, for example.
Vintage slot machine mechanics can only have so many symbols on the reels before the game are literally and physically too big to be practical. But a game powered by a computer may have 20 symbols per reel.
