The skill component, retro style and engaging gameplay make Mega Joker a firm favourite with players. It is this element of skill which can increase the RTP. In Supermeter mode, you need to choose the bet level and the optimum level at which to collect your winnings. Furthermore, it provides bigger payouts and the Supermeter mode. Yet on the other hand, a max bet of 10 coins elevates the RTP to between 89.1% – 99%. Bet with just 1 coin and the RTP is an underwhelming 76.9%. Whilst Jackpot 6000 boasts an extremely high RTP, it is just beaten to the top spot by another NetEnt classic slot Mega Joker. With this in mind, I have decided to create a list of the 10 online slots with the highest RTP. The return to player percentage of a game is measured over thousands of game rounds, and it stands to reason that the higher the RTP, the better the deal for the player. Of course, you should keep in mind that only the best slot sites to win offer high payout games from which you can take advantage.
