Return to Player or RTP is used to express the game’s theoretical payout percentage, i.e. how much of the money you have wagered will be paid back to you over time. For example, if a particular game has an RTP of 95%, it means that players can expect to receive back €95 in winnings for every €100 they bet, at least theoretically.
However, there are two things that players need to be aware of. Firstly, no matter how accurate the RTP of a particular game is, it only represents the average return over extended periods of time. If a player’s betting session is quite short, the actual RTP may differ significantly from the statistics published by the online casino.
Therefore, in the case of crypto roulette, the RTP represents the average return for many spins over extended periods of time. In other words, the more spins the wheel takes, the more accurate the actual roulette return information will become.
Another thing to keep in mind is that the RTP does not function as an indicator of how often you win at roulette (or any other game). The RTP published by a particular online casino is the same for all the types of bets you can place at live Bitcoin roulette. But if a player only places even bets, such as Black/Red or Even/Even, they will certainly receive payouts more frequently than a player who bets on single numbers.
According to European and American roulette rules at Bitcoin roulette casinos, the player loses every time the ball stops on zero. American roulette has two zeros (a single and a double zero) so the chances of winning are 1 in 38, which results in an RTP of 94.74%. European roulette, on the other hand, has only one zero, so your chances of winning in this version are 1 in 37, leading to an RTP of 97.3 %.
