The Different Types of Slot Machines


Whether you are playing for fun or a serious player, you should know that there are different types of slot machines that you can choose from. Some are mechanical, while others are electrical. The payback percentage is another factor that you should know about.

Video slot machines

Unlike classic three-reel slots, video slots have dozens or even hundreds of paylines. This allows the player to have more chances to win and has the potential to bring home a bigger payout.

Some video slots also offer bonus games, such as free spins and scatter pays. There is also the chance to win a progressive jackpot, which increases with every bet you make.

Most video slots use a Random Number Generator (RNG) to determine the outcome of the game. This is a computer program that picks a series of numbers and displays them on the screen after the reels have stopped spinning.

Electrical vs mechanical machines

Regardless of whether you play at a land based casino or at an online casino, there are two main types of slot machines – mechanical and electrical. Mechanical slots use mechanical components to spin the reels, while electrical slots use a computer chip to determine the outcome.

The first slot machines used cams, levers, springs, electro-magnets and solenoids to rotate the reels. As the technology improved, the machines began to use more complicated designs.

Mechanical slots can be divided into two basic types: three-reel, or “one-armed bandit,” and five-reel, or “multi-arm bandit.” The first mechanical slot machine was dubbed the “Liberty Bell” and was invented by Charles Fey in 1895.

Payback percentage

Choosing a slot machine with a high payback percentage increases the chances of winning. A machine with a 95% payback rate will give you back ninety cents for every dollar you wagered.

A slot machine’s payback percentage can vary from machine to machine, and can be influenced by the design of the slot machine. Features such as bonus rounds can also increase the payouts.

The most important factor to consider when choosing a slot machine is the payback percentage. This percentage is calculated by comparing averages across a group of slot machines. A higher payback percentage increases the odds of winning, and is therefore more profitable to the casino.
