Slot machines online

Slot machines are like anything else—they can be categorized into various types. These categorizations can be based on a number of different factors. This page looks at some of the most common ways of dividing slots into types.

Denominations

One of the easiest ways of organizing slot machines into different types is by looking at their denominations. Some games only accept pennies, while other machines only accept dollars. Some games allow you to choose from multiple dominations.

The most common denominations for slots play include:

Number of Reels

The spinning symbols on the front of the machine are called “reels”. They used to be large hoops made from metal that physically spun inside the machine, but now they’re usually just for show. In fact, on most modern slot games, these reels are just video screens.

Traditional old-school slot machines have three reels, but more advanced slot machine games use five reels. The additional reels make it possible to have even larger jackpots, because it’s correspondingly harder to win on a game with the additional reels.

Game Type

Slots have changed a huge amount over the years going from very basic games with 3 reels to highly interactive games with feature-rich 3d video and immersive sound. Furthermore, you can find different variations of the machines depending on where you are in the world. The list below covers the main types.

Class II and Class III Slot Machines

Various jurisdictions in the United States categorize slot machines into one of two classes—class II games and class III games. The latter are the traditional slot machine games you’ll find in Las Vegas, Reno, Atlantic City, and other large gambling destinations. The former are usually found in smaller gambling destinations, often in states which only allow casinos operated by local Native American tribes.
