Casinos with the Highest RTP: Ranking of Platforms with Returns of Up to 100% in 2025

In online casinos, the key indicator of player benefit is RTP ( Return to Player), which reflects the percentage of bets returned as winnings. The optimal RTP starts at 96% and can reach 99%, as in popular slots like Ugga Bugga (99.07%) or Mega Joker (99%), both available on reputable platforms. In 2025 , the focus shifted to licensed sites partnering with trusted providers like Push Gaming (with a guaranteed 96%+) or NetEnt (up to 97.5%), eliminating the possibility of percentage manipulation . For example, Duel Casino platform stands out withan RTPof up to99%andfastprocessing,makingitaleaderamongthose who appreciatehighodds.LearnmoreaboutRTPprinciplesinour main review.

Benefits of high RTP casinos

The role of providers in ensuring RTP: Developers like Push Gaming and Relax Gaming play a key role, providing slots with RTPs of 96% to 99% on compatible platforms. Pragmatic Play’s software offers the option of setting RTPs up to 98.5%, but we at Gambler don’t trust this provider. For more details, see the RTP provider section.

Top 5 casinos with the highest RTP

We present a ranking of platforms with an RTP of 96% or higher, based on payout speed, reliability, and access to high-return games. Only licensed sites with verified providers are included.

Duel Casino (RTP up to 99%): A leader with a 400% bonus + 200 FS and payouts in 1–120 minutes. Suitable for slots with the highest return, such as Blood Suckers (98%). Learn more about Duel Casino.

Cactus (RTP up to 98%): A platform with a 300% bonus + 100 FS and payouts up to 60 minutes. It features NetEnt games with high RTPs. Learn more about Cactus.

Mathematically, a 4% RTP spread can double the payout of a slot. Example: The same slot has a 96% RTP in one casino and a 92% RTP in another. This means that the casino with a 96% RTP has a twice-higher chance of winning big.

But judging by the ratings of reputable providers, RTP doesn’t always determine the outcome. The chances of winning big in slots from Push Gaming with an RTP of 96.5% are higher than in slots from Pragmatic Play with an RTP of 98%. Our 10 years of gaming experience confirms this!

If this applies to untrustworthy casinos where Play n GO slots are set to 84%, then the chances of a big win are practically nonexistent. However, this provider is quite good if the RTP is set to 94%.
