# How the Reels and Symbols on a Slot Machine Work

The Reels and Symbols on a slot machine are what determine the outcome of your spin. The Random number generator determines the outcome of each spin. Multi-coin/multi-line slot machines allow players to choose how many lines to play. They can also be configured to be tighter or looser. In some cases, players can adjust the odds of their machine by changing the computer software. However, this type of slot machine is not for the faint of heart.

## Symbols on a slot machine determine whether you’ll win

Slot machines have a certain number of paylines, or ways to make a winning combination. There are usually ten, twenty, thirty, or even fifty paylines, depending on the game. Winning combinations happen when the same symbols appear on one or more paylines. When a winning combination occurs, the paytable will display how much each symbol will pay. Symbols that are on the same payline will win a smaller payout than those that are further apart, but they will increase the amount of money that you win.

## Reels on a slot machine determine whether you’ll win

You’ve probably wondered about how the reels on a slot machine work. After all, these are simply large metal hoops, but in reality, they are images that spin on a video screen. Regardless of the shape and number of reels, how do they determine whether you’ll win? The early slot machines used mechanical wheels that stopped at specific positions. While these still determine the outcome of each spin, the technology has advanced greatly.

## Random number generator determines the results of each spin

The random number generator, or RNG, is the brain of a slot machine. Unlike traditional machines where you can control the outcomes, this technology is unbiased and cannot be influenced by your actions. Slot machines are programmed to produce random numbers on a fixed frequency and payout ratio. The RNG produces random numbers every millisecond and determines the outcome of each spin. Because of this, the results of any spin are unpredictable.

## Multi-coin/multi-line slot machines allow players to choose how many lines to play

The multi-coin/multi-line slot machine is a great option for a beginner, since it gives the player flexibility to decide how many lines they want to play. In general, the math shows that the more lines you activate, the higher the hit frequency, but in the case of a multi-coin machine, the worst payout you can expect is a push. For example, if you hit a cherry on the second payline, your payout will be two coins. However, it can be a frustrating experience when a winning combination occurs on an un-activated payline.

## Buy-a-pay slot machines allow players to set a win limit

A Buy-a-pay slot machine allows players to set a maximum amount of coins that they will wager. By doing so, the player will unlock extra winning combinations every time they bet a coin. Because the frequency of hits depends on the number of coins wagered, a single coin can mean the difference between a 100% payback and an 84% payout. To avoid this pitfall, players should always wager as many coins as they can afford.
