What is a Payout Percentage in a Casino?
A payout percentage, also known as Return to Player (RTP), is a measurement that comes up a lot in the online gambling world. It represents the amount of money a casino game returns to players on average and over an extended period of time.
💡 For example, if you play a slot with a 98% RTP, you can expect a return of €98 for every €100 wagered, theoretically. This average is calculated across all players, so sometimes you can come away with a lot more and sometimes a lot less.
How is RTP Determined
These percentages are calculated through testing by independent 3rd party organizations like eCOGRA and iTech Labs. These institutions are responsible for conducting audits of casino games to ensure fairness and transparency. Simulations that mimic real-world play are run, to ensure the random number generator (RNG) algorithms are legitimate and cannot be rigged. This guarantees that the RTP figures advertised by online casinos are accurate and reliable.
Games with higher RTP rates have a greater potential to provide the player with chances of winning. Again, this is purely based on averages. However, it still remains a key factor when choosing where to play. This guide will delve into the best payout online casinos, helping you make informed decisions for your gaming needs.

5 Best Payout Casinos – 2025
The number of choices when it comes to online casinos is truly staggering. Even when filtering down to the best paying online casino sites, you are still left with a lot to choose from. After extensive research and comparison, I recommend the following five best payout online casinos for 2025:
You can view a larger selection of top 10 online casinos Ireland with the best payout.
Dolly Casino excels with its high RTP slots and attractive bonuses. The welcome pack includes deposit bonuses up to €1000, spread across your first three deposits. This online casino with best payout offers excellent RTP rates, a variety of payment methods, and fast withdrawals.
However, the site would be much improved with a dedicated mobile app and more contact methods to reach the support team. Despite these minor drawbacks, Dolly Casino provides a solid gaming experience with a focus on player-friendly features and efficiency.
Jackpot City is a well-established online casino known for its generous bonuses and extensive game selection. The welcome package provides players with up to €1600 in bonus money, as well as 80 free spins that can be claimed separately with a deposit as low as €1. The customer support team is accessible and can be contacted via live chat on a 24/7 basis.
The drawback to all of this is that many Jackpot City offers do come with higher-than-average wagering requirements. The previously mentioned free spin package, for instance, comes with an unusually high 200x wagering requirement, and there is also a weekly withdrawal limit cap of €4000. With that being said, if you make sure to read the fine print of the promotions, you are sure to have a good time.
Dublin Bet offers a unique blend of traditional and live casino games, catering to novice and experienced players. The welcome package is a modest bonus of up to €250 spread across your first two deposits, but it does only come with a 30x wagering, which is lower than the industry standard.
What lets the site down the most is that the customer support team is not available on a 24/7 basis. If you can see past this, you will find a stacked games lobby and accessible user interface that can be enjoyed on both desktop and mobile. There is also something to be said with the on-point branding that specifically caters to Irish players, making this one something you should at least check out for yourself.
LeoVegas is an award-winning brand known for its mobile-friendly platform, extensive game selection, and best payouts. The welcome pack is generous, offering up to €1000 in bonus funds and 200 free spins. LeoVegas stands out for its high-quality mobile experience, large game selection, and regular promotions.
On the downside, the wagering requirements are higher than average, and there is a sense of suffering from success when it comes to contacting the customer support team, which can be slow at times. Overall, LeoVegas is an excellent choice for players seeking a seamless mobile gaming experience.
888 Casino is another established name in the online gaming industry, and is known for its reliability and diverse game offerings. New players can benefit from a €1500 welcome package, as well as numerous offers on further deposits.
However, withdrawal options are limited, and newer players may be confused by the fact that the 888 brand is split across multiple websites. Despite this, 888 Casino remains a top choice for many players due to its solid reputation, online sports betting option, and extensive game lobby.
