The Best Payout Online Casinos UK

How Online Casino Sites Available in the UK Calculate Their RTP

Online casinos in the UK Sites calculate their RTP rates by considering the RTP percentage of all their individual games and bonuses. Independent auditing firms, such as eCOGRA, GLI, and iTech Labs, also verify the RTP of online casinos and gambling games in the UK.

Consequently, the best payout online casinos in the UK have excellent promotions available, such as no deposit with bonuses low or zero wagering requirements. This is because gamers who have effectively paid nothing or very little to unlock free wagers can receive payouts disproportionally higher than what they paid in.

3. Roulette

Whether online or in-person games, roulette has a shared high RTP (around 96%). However, some games boast a house edge as low as 1.36% (RTP 98.64%) if the En Prison or La Partage rule is applied.

4. Video Poker

This popular online casino game has an average payout rate of 95.43%. Yet some video poker games can have a low RTP, so always check this before wagering.

5. Baccarat

Baccarat is a high-stakes game with a 98,91% RTP on average. Still, be aware that the RTP for the Banker bet is slightly higher than the RTP for the Player bet, and the tie bet wager is the lowest.
