Types of Online Slots in Irish Casinos for 2025

A great deal of the fun that online slots offer is the wide range of their diversity. Hundreds of software developers create games for the online market, supplying casinos with thousands of titles and constantly adding more. Since there are so many slot machines on offer, casinos tend to categorise them for easier navigation and selection. Below are some of the categories you’re likely to see at online casinos in Ireland.

Video Slots

Video slots are the broadest category since all games with themed graphics and special features fall into it. There are infinite topics that affect game design and make each slot feel new and different. Video slots frequently feature new structures and word changes that make the gameplay more fun.

3-Reel Slot

3-reel slots are sometimes referred to as classic slots because they are a return to the very first slot games. Their attractiveness is due to a simple layout and classic symbols like fruits, BARs, bells, lucky 7s, or stars. Some players like simple gameplay without the complexity of features, so classic slots are still as popular as they were in the past.

High RTP Slots

High RTP slot machines provide better returns over the long run. RTP (Return to Player) is the percentage of the money staked that the slot machine returns to the player over a period of time. So, a slot machine with 97% RTP is supposed to return €97 for every €100 staked over a certain period. The higher the RTP, the better the player's chances.

Progressive Jackpot Slots

Progressive jackpots provide the firsts that become more giant with each new player’s wager. A portion of each wager goes into the jackpot pool until someone wins. Afterward, it resets to a base amount. Some jackpots come about completely at random, while others need you to access a special bonus round to get them.

Low Volatility Slots

Volatility is a measure of the frequency of a slot machine's winnings and the size of those winnings. Low volatility slots award smaller but more frequent wins, while high volatility slots give larger sums less often. Your budget and risk appetite will decide which is right for you.

Megaways Slots

After the release of Bonanza by Big Time Gaming in 2016, Megaways slot games had worldwide success. Today, hundreds of Megaways slots exist, featuring up to 117,649 winning combinations per spin thanks to their dynamic reels.
