Cluster-type games don’t have traditional win lines and matching symbols don’t have to be on adjacent reels either. What players must land in games that apply these mechanics is clusters of a certain number of same symbols that must be adjacent to one another vertically and horizontally.

Cluster Tumble slot features six regular symbols. Three types of gems that come in red, green, and blue colours are of the lower-value end. More valuable symbols are a blue Aztec head, a green scarab, and a pink dragon. The game has a Wild symbol as well, marked with a letter W. The wild can replace any of the symbols.

When you start the game, only certain grid positions are open and as you play and win further positions open allowing new symbols to fall in.

If you manage to remove all stone blocks during your gameplay or if you land 3 Scatter symbols you will be awarded Free Spins. To start with, you receive 5 Free Spins and clearing the board will earn you 3 more along with a 3x multiplier. Every time you then land a Scatter you get an extra Free Spin.

The Lightning and Fire special symbols trigger the Lightning win, and the Fire transform features. The Lightning win feature replaces the special stone block by a regular symbol, the target symbol. This newly determined symbol can earn you wins no matter where the symbols are on the grid. The Fire transform feature is similar to the Lightning win feature but here players have a chance of transforming 2 stone blocks.

You can decide to buy Standard or Volatility Free Spins any time you wish for 100x and 200x the bet, respectively.


Cluster Tumble comes with high volatility where most wins happen while the bonus features are activated. The RTP of Cluster Tumble is 96.40%, a figure that is just a little above average. During Free Spins the RTP is slightly higher.


Cluster Tumble has lots of potential due to its high maximum win figure. If you like Guts casino treasure-hunting themed slot machine games online, you’ll most likely enjoy this nicely animated and immersive game. The progress of the game opens new positions and becomes satisfying.
