Cluster Tumble drags you deep into the crumbling temple ruins of the Himalayas, helping a fearless explorer track down her missing husband, a nod to the hero of Temple Tumble. Relax Gaming has built a punchy cluster pays slot with a serious kick under the hood.

Casinos with the highest RTP for Cluster Tumble

We check every casino's RTP setting for Cluster Tumble regularly, and the list below updates straight from our database. Base RTP sits at 96.40%, climbing to 96.47% if you buy the standard bonus, or as high as 96.57% with the volatile bonus buy.

How many spins do you get

The gap in spin count between RTP levels is bigger than most players think. Take a look at our calculator below for Cluster Tumble.

If you start playing with $200 and bet $1 per spin, we can compare how many spins you get depending on the payout level.

At the highest level of 96.4%, you theoretically lose 3.6% of your bet per spin, which equals $0.04 per spin. That gives you approximately 5 556 spins before your budget runs out.

At a lower payout level of 94%, the theoretical loss is 6.0%, which is $0.06 per spin. That means you can spin approximately 3 333 times before the money runs out.

The difference is 2 223 spins between these levels – quite a significant difference when you think about it!

Bonus round and features

Free spins unlock by landing 3 scatters, the temple gates, or by clearing every stone block on the grid. Either route hands you 5 free spins.

The grid hides stone blocks with special effects. Some turn into a Wild once a win lands next to them, others become a Lightning Win that pays for every matching symbol regardless of position, and a third type turns into a specific symbol via Fire Transform.

Clear the entire board during free spins and you bank a multiplier starting at 3x, climbing by 3x with every full clear, plus 3 bonus spins. A scatter landing during free spins adds one more spin.

Want the action right away? Bonus buy comes in two flavours: the standard round costs 100x your bet, while the volatile version costs 200x but starts the multiplier at 6x, climbing by 6x per full clear.

Cluster pays, paylines and RTP on Cluster Tumble

Cluster Tumble is played on an 8x8 grid, though only part of the board is active at the start, the rest sits blocked behind stone tiles you gradually clear. A win needs at least 4 connected matching symbols, horizontally or vertically.

Hit frequency lands at a slim 20.29%, which paired with the high volatility makes this a genuine test of patience. Bets range from C$0.10 to C$50 per spin, and the max win tops out at a staggering 20,000x your stake, one of the biggest ceilings in the whole Tumble series.

Paytable and symbols

The Wild symbol carries up to 5 lives and substitutes for every regular symbol, losing one life each time it lands in a win. Below is what every symbol pays depending on cluster size.
