Cluster Tumble is a slot developed by Relax Gaming with an engaging visual design. The game features a 8-reel, cluster pays layout with an RTP of 95.08% and very high volatility, offering impressive win potential for players of all experience levels.
At 95.08%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
Very high volatility delivers the most extreme payout profile — long dry spells punctuated by potentially massive wins. Only recommended for experienced players with substantial bankrolls and high risk tolerance.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Cluster Tumble features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
Instead of traditional paylines, Cluster Tumble uses a cluster pays system where wins are formed by groups of matching symbols touching horizontally or vertically. The larger the cluster, the bigger the payout. This mechanic opens up many more potential winning combinations than fixed paylines.
3.0 / 5 — Good
Cluster Tumble by Relax Gaming is a solid offering that delivers good entertainment value. The 95.08% RTP combined with very high volatility creates a well-balanced gaming experience.
