The average RTP (Return to Player) rate for an online slot is around 96%. Anything above 96.5% is generally considered to have an appealing payout percentage, and games like Blood Suckers stand out by offering an unusually high rate.

You'll find most online slots hover right around the 96% mark for RTP. That means slots with RTP percentages higher than 96% can be considered higher than average. Sometimes progressive jackpot slots will have lower RTP percentages, with the chance of winning big jackpots making up the difference.
