Slot Machines – How Do They Work?


The game of slot is as popular as ever. Whether you call them fruit machines, pokies, fruities or one-armed bandits, slots are the world’s most popular casino game. But how do they work, and what makes them so successful? Read on to find out all you need to know about the game’s odds, rules, symbols and more.

The first step is to understand how paylines work. Basically, the machine’s RNG generates a sequence of numbers that correspond to the stops on the reels. The sequence is then divided by a standard number to produce a quotient. The computer then finds the corresponding reel stop and maps it to a particular symbol in the slot. If a winning combination of matching symbols is triggered, the player wins.

Some modern slot machines feature multiple paylines. For example, some have 243 or 1024 ways to win. The number of paylines determines the house edge and how much chance there is of hitting a winning combination on a given payline.

Another important factor in the house edge is the number of reels and symbols. Each additional reel or symbol increases the probability of hitting a specific symbol, but also decreases the chance of hitting the jackpot. It’s important to balance the house edge with how many coins you want to play per spin.
