Cluster Tumble

Cluster Tumble Slot Game Overview

The bet sizes available in Cluster Tumble range from 10p to £12.50.

This game does not feature paylines, instead using a Cluster Pays mechanic.

Special Stone Blocks

When you complete winning combinations in this game, it is possible that you may activate some adjacent stone blocks. These can then add special bonus features to your gameplay, as outlined below:

Lightning Win: This special stone block will be substituted for a target symbol whenever it is triggered. Target symbols are one of the regular symbols within this slot. The Lightning Win will take effect after the upcoming cascade, and it causes all matching symbols with the target to form a win irrespective of their position on the board; this includes Wild symbols.

Wild: You can use Wild symbols as substitutes for all regular symbols in Cluster Tumble.

Fire Transform: When you activate the Fire Transform feature, the stone block will be substituted for a target symbol. On your next cascade, either one or two symbol types will turn into the same symbol as the target.

Free Spins

Hit three Scatter symbols or remove all of the stone blocks from the board to trigger the Free Spins bonus round.

You will receive five free spins when this feature begins.

If you manage to clear all of the stone blocks on the board during Free Spins, you will unlock three extra free spins, and also increase the win multiplier.

The win multiplier's value is enhanced by three whenever you clear the board. So for the first removal, the multiplier is 3x, then 6x, then 9x and so on.

Multipliers take effect as soon as they are activated and remain in play for the duration of Free Spins.

One additional spin is awarded when a Scatter symbol appears on the grid during this bonus round.

Return to Player

Return To Player (RTP): 96.40%.

The expected return is the amount we pay out to players relative to the amount of wagering on the game.

For example, if we take £100 of wagers we will, on average, pay out £96.40.
