Payout Percentages at Irish Online Casinos
BonusFinder has listed all the online casino sites with the highest payout percentages. We consider a high paying casino to return at least 97 % back in the long run. Generally speaking, any casino online offering a payout percentage above 97% is a great place to game. Choosing betting sites or a casino in Ireland with the highest payout percentage possible is the best way to maximise your odds on winning.
However, new online casino sites are pushing the envelope by offering juicier real money slot machines and table games. Some might find the above results surprising. However, we’re not shocked – thanks to their brands, established online casinos can get away with lower payout percentages. Meanwhile, new online casinos have to fight over market share.
We have a separate page about the fast payout casinos in Ireland. If that’s an important detail for you, we suggest taking a look at that page.
Casino bonuses and high RTP online casino games
Claiming casino bonuses is the first step to increasing your return to player %. However, you must be aware that casino operators often exclude certain games from the wagering contribution in their casino bonuses. And this is due to the high RTP of some games.
Live casino games are a clear example of the type of games you will find excluded most times. Fortunately, the team of experts at BonusFinder have gathered all the best live casino deposit bonus offers, where the wagering contribution of these games is as high as 100%.
Best Paying Casino Games
The average payout percentages vary between casinos. In 2025, almost all casinos list the theoretical payout percentages of each game. It’s important to keep in mind that you’re not able to play all the games with your casino bonuses. Table games (Online Baccarat, Online Roulette, Online Blackjack) and most live dealer games also have such high payout ratio that casinos won’t allow you to play those games with the extra money you receive from their generous welcome bonus.
These live dealer games have the smallest house edge, which means that they are theoretical highest payout casino games. The average percentage payout rate changes significantly between playing online slots, and for that reason, you are not allowed to play some of the games with bonuses.
| Casino Games | Payout Rates |
|---|---|
| Online Slots | 92-98.5% |
| Video Poker Games | 99.5% |
| Live Blackjack | 99.5% |
| Live Baccarat | 98.9% |
| Live Roulette Games | 97.3% |
| Craps | 98.64% |
Highest Payout Online Slots
Online slots with the best RTP are the most popular online game type in the casino industry. Compared to live casino games (usually provided by Evolution Gaming or Pragmatic Play), the best online casinos usually offer hundreds of different gambling game options in their slot game library.
Playing online slots with casino bonus offers is the best use of your welcome bonuses as slot games usually contribute 100% towards wagering requirements.
| Slot | Provider | RTP Percentages |
|---|---|---|
| Mega Joker | NetEnt | 99.0% |
| Uncharted Seas | Thunderkick | 98.50% |
| Mega Moolah | Microgaming | 96.92% |
| Immortal Romance | Microgaming | 96.8% |
| Tropic Reels | Playtech | 96.8% |
| Great Rhino Megaways | Pragmatic Play | 96.58% |
| Book of Dead | Play'N Go | 96.21% |
| Fire Joker | Play'N Go | 96.15% |
| Starburst | NetEnt | 96.1% |
| Book of Ra | Novomatic | 96.0% |
Great Rhino Megaways slot is excellent for using your casino bonuses. It’s a highly volatile slot game where you have a chance to hit massive wins on unlimited multipliers.
Some top online casinos even offer free spins with no deposit required to try out and play other casino games. Most of the top paying casinos listed here allow you to play any progressive jackpots or video slots with your casino bonus funds.

How to Make Sure a Casino is Safe?
We all want to play on sites with the best online casino payouts. So choosing a gaming site with the best online casino payout will help you enjoy a better online gaming experience. Here are a few ways to track down operators that payout the most:
- Choose online casinos promoted by BonusFinder – The majority of casino operators we recommend have high payout percentages. Now, this number can shift from year-to-year, but we always aim to promote exciting, high-paying online casinos. We stay on top of online casino payout percentages, so you don’t have to.
- Check their eCOGRA listing – Many of the best online casinos in Ireland contract eCOGRA to test the random number generator software of their casino games. As part of the certification process, eCOGRA publishes the online casino’s total RTP, or return-to-player percentage. The closer that number is 100%, the better online casino payouts you can get.
- Gambling License – We only recommend playing in the best online casinos with official gambling licenses from reputable gambling authorities.
- Evaluate their welcome package/ongoing promotions – The RTP of an online casino’s games determines its payout rate. However, you should also take reload bonuses into account. Evaluate the casino bonus cash and free spins they award and their wagering requirements. The more player-friendly there are, the more these deals payout.
Use the above-listed methods for up to date information, and you’ll find a casino in Ireland that’ll offer casino players chances to play games available for real money.
