So, what exactly is a “fair” online casino? While fairness means different things to different players, there’s one useful starting point: return to player (RTP). 

RTP indicates the theoretical amount a game returns to players over time. The higher the RTP, the lower the house edge, aka the casino’s mathematical advantage. Most casinos will feature RTP games around the 90-97% rate. However, that traditional model is being challenged by a select number of platforms. 

Here are the leading platforms going to the next level when it comes to RTP.

1. Duel

Out of every casino on the planet, Duel takes the most noteworthy stance when it comes to RTP and fairness. That’s because every original in-house game has 100% RTP. That means there’s no house edge. There’s no mathematical advantage as found with virtually every other casino game. 

A 1% difference from 99% to 100% might seem insignificant. However, its effect accumulates across repeated bets. By removing that edge entirely, it changes the long-term mathematical relationship between the player and the game. 

The selection of originals includes everything from Plinko to Rock Paper Scissors. If you’re looking for the fairest blackjack table, you’ll find it at Duel. The fairest slot in Groomer’s Van is here. The same is applicable to video poker, keno, crash-style games, and more. This in-house range offers different ways to play while sharing the same zero edge approach. 

Duel also applies provably fair technology to all its proprietary titles. Before a round, its system generates a server seed, combines it with the player’s client seed and a nonce, and commits to the server seed through a SHA-256 hash. After the game, you can verify the revealed seed and check it matches the original commitment. This gives you a way to directly examine how outcomes were generated. 

2. Cloudbet 

When comparing RTP, Cloudbet is another crypto casino near the top of the list. Its original games reach the 99% RTP mark, putting them close to the theoretical return offered by Duel’s in-house titles. Although that remaining percentage, small as it is, still represents a mathematical house advantage. 

Over time, that distinction is important. RTP describes a long-run statistical expectation, not a promise about an individual session. That means, even theoretically, a 150% RTP game still produces losing streaks. However, by comparing RTP figures, it allows players to judge based on the underlying mechanics.

Cloudbet also offers provably fair gaming, giving members another way to assess fairness beyond the published return percentage. 

3. Bitcasino.io

Bitcasino.io provides another example of how RTP can vary between individual games. For instance, its in-house blackjack offering is particularly notable for a 99.46% RTP. This places its theoretical return relatively close to 100% while retaining a minimal yet significant house edge. 

That fraction of a percentage point appears minor, but the difference becomes more relevant when factoring in repeated play. Either way, the higher the RTP, the better it is for players in general. 

Bitcasino.io, like the other two mentioned casinos, also features provably fair gaming. This supplies a further point of comparison for those assessing casino transparency.
