Casumo Casino has added a new Relax Gaming slot to their casino, released on the 3rd of November 2021. The aptly named Cluster Tumble slot is the 5th release in the “Tumble Series” of machines from Relax Gaming and sees the intrepid female explorer on a mission to rescue her husband and collect a few riches on the way.

As you would expect from the game title, this slot focuses heavily on the Cluster Pays format, followed by Tumbling Reels for new wins. If we were scoring game titles, this release wouldn’t be scoring very highly for originality.

Gameplay takes place on an 8×8 grid but with a limited number of starting symbols present in the middle of the grid. You need to create wins to break blocks to expand the playable grid area and reveal any special feature symbols.

Cluster Tumble is another high variance, and volatile slot from Relax, with a volatility rating of (5/5) with max wins capped at 20,000x stake.

We have included the free to play demo version above, including the bonus buy options (normal and volatile). Test this slot out for free and get a quick understanding of how the free spins round works and the potential this slot has to offer!

Cluster Tumbles Slot –  Base Gameplay

The base gameplay on Cluster Tumbles is an unusual one but also quite simple to sit back and watch the action and consecutive wins unfold.

Gameplay takes place on an 8×8. On each spin, there is a random number of starting active pay symbols on each spin. These appear in the centre of the grid. Clusters of matching symbols are required to form wins that can include Wilds.

Wins must be formed to destroy all the surrounding blocks. This increases the number of active symbols in play thanks to the tumbling reels and may unlock some of the unique feature symbols that are present but not currently activated.

Base Game Features

Both the Lightning Win and Fire Transform features can help quickly destroy many of these blocker symbols, giving you a better chance of scoring additional wins or even fully clearing the grid!

The main bonus round can be triggered in 2 different ways. Firstly, regular scatter symbols are present on the reels, and three are required to activate the free spins feature. The alternate bonus trigger occurs if you manage to destroy all of the blocks on the grid in the base game.
