3-Reel Online Slots

3-reel online slots are the simplest options on the market, calling back to the original game designs of yesteryear. These classic-style games are getting harder to find in the modern online casino landscape, but there are a few still going.

These include Triple Diamond and Wizard of Oz – 3 Reel. 3-reel games typically have a maximum of five pay lines – one across each row and two diagonals.  

5-Reel Online Slots

The most common type of online slot is the 5-reel offering, which has five reels that spin independently of one another. These will usually have three rows, but some modern slot developers have increased this to a grid format. 5-reel slots enable a vast number of paylines, as symbols can match across various combinations.

The minimum number of paylines on these games is 25, but there are some offerings like Game of Thrones that have 243 ways to win.

Progressive Slots

Progressive slots are online slots that are linked over a sprawling network. Players from all over the world can play the same titles and, when they do, a portion of their stake contributes to a rolling jackpot. These games list the jackpot at the top, so you can see how high it is. The jackpots are programmed to pay out after reaching a specified figure or after a certain amount of time.

There have been some famous cases of progressive slots paying out lottery-like winnings to players in the past. The best-known game of this type is Microgaming’s Mega Moolah, which rewarded over $21 million to one lucky player on the Isle of Man in 2018.  

Online Slots – Glossary

Active Payline

Slots with several paylines usually allow players to choose how many they want to activate on each spin. By activating more lines, you increase the stake of each spin. When winning combinations land on an active payline, you get a return on your stake.

Auto Play

Most online slots have an auto play button, meaning that you can leave the reels spinning for a desired number of times without having to press spin each time yourself.

Bonus Feature

Some modern slot games come with a bonus feature. This can be activated by landing winning combinations, and it usually gives you a chance to win the top prizes.

Fixed Jackpot

A fixed jackpot is when the grand prize is listed on a game, and it pays out the exact amount when you win it.


A multiplier is when winnings are multiplied by a certain amount. This can often appear during the bonus feature, and it helps activate the top pay-outs.

Progressive Jackpot

A progressive jackpot is a rolling jackpot that pays out to one lucky winner in a lottery-like system.


RNG stands for random number generator. Every online slot game uses RNG to determine where the reels land. This means that the games are fair for all players.


RTP stands for return to player. This is listed as a percentage, and you can find this in the slot’s information page. It means that a slot theoretically pays back a certain amount to players. For example, if the RTP is 96%, it should pay out around $96 to every $100. This isn’t exact, though, and other factors such as RNG have an influence.

Wild Symbol

Nearly every slot game has a wild symbol that can replace any other symbol in the game to create winning combinations.
