Return to Player (RTP) is a crucial metric for any online casino player, indicating the theoretical percentage of all wagered money a game will pay back to players over time.1 In 2025, new UK online casinos are not just offering a wide variety of games; they’re also highlighting those with high RTP to attract and retain savvy players.2
For a new casino to be competitive in the UK market, it needs to provide a diverse selection of high-RTP games from top-tier providers. While most players are familiar with RTP, knowing where to find the highest-paying new online uk casinos games at new sites is key to a rewarding experience.
Why High RTP Matters for UK Players
A game’s RTP is the inverse of the house edge. For example, a slot with a 96% RTP has a 4% house edge, meaning for every £100 wagered, the game is expected to pay back £96 in winnings over its lifetime.
While RTP doesn’t guarantee a win on any single spin or session, playing high-RTP games statistically improves your chances of winning in the long run.3 This makes it a popular strategy for players who want to maximize their returns and prolong their entertainment.
How to Find High-RTP Games at New UK Casinos
The best new UK casino sites make it easy for players to find the RTP of their games.
- Check the Game Information: Most modern slots and table games from reputable developers will have their RTP clearly stated in the game’s paytable or information section. This is usually accessible via a small “i” or settings icon within the game.
- Use Casino Filters: Some advanced new casinos, like Bet365 Casino, offer a filter tool in their game lobby that allows you to sort games by RTP.4 This is an excellent feature that demonstrates a commitment to transparency.
- Consult Reputable Review Sites: Independent casino review sites and industry publications often list the RTP of popular games and highlight new casinos that offer high-payout slots. This is a great way to discover new high-RTP games and the sites that carry them.
High-RTP Games to Look for in 2025
While classic games like Blackjack and French Roulette are known for their high RTP (often over 99% and 98% respectively, with optimal strategy), here are some of the standout high-RTP slots and games to look for at new UK casinos in 2025:
- 1429 Uncharted Seas (Thunderkick): This slot consistently ranks among the highest, with a remarkable RTP of 98.6%.5 Its nautical theme and engaging gameplay make it a firm favourite.
- Mega Joker (NetEnt): A classic fruit machine-style slot with a potential RTP of up to 99%, though this requires playing in “Supermeter Mode” and using optimal strategy.
- Blood Suckers (NetEnt):7 With a vampire theme and a high RTP of 98%, this slot is a great choice for players who want both a fun theme and a high payout percentage.
- Book of 99 (Relax Gaming): A “Book of”-style slot with an impressive 99% RTP.9 However, it’s important to note that not all casinos offer the game at its highest RTP setting, so always check before you play.
- Marching Legions (Relax Gaming): This slot offers a 98% RTP and the chance to win up to 10,000x your stake, making it an appealing option for those seeking both high RTP and high-payout potential.
- Blackjack and Roulette: For table game enthusiasts, seeking out a new casino that offers European or French Roulette (with a 97.3% or 98.65% RTP respectively) and a wide variety of Blackjack tables (where RTP can exceed 99% with optimal strategy) is a smart move.
