It is important to understand that the RTP never shows 100% return.

Despite how much time the player spends at a particular slot machine, it will not be possible to control the payout. The program does not choose when and who to give the laid down RTP. Even after getting a quick win, the game will still take its percentages for a long distance. The best slots with high RTP are presented in the table.

Snake 98%
Bikini Queens 97,77%
