Cluster Tumble RTP and Wagering

Cluster Tumble, as its name might suggest, uses a cluster-pay gameplay mechanic. This means wins are formed whenever players land symbols in a cluster of four or more. They must touch one another vertically or horizontally to be considered part of a cluster. Like most cluster-pay slots, the game takes place on an enlarged game grid with eight reels and eight rows. 

However, despite the enhanced grid size, only 15 symbols land on each base game spin. The rest of the positions are blocked off by stones. Whenever you land a winning cluster, it explodes and will open up other symbols. This continues happening until no new winning clusters are formed, with the reels resetting at the end of a cluster. 

You can adjust the stake on each spin, with a minimum of £0.10 and a maximum of £50. The slot game has some good winning potential, serving up a maximum win of 20,000x your stake. The RTP of the game is 96.40%, which is comfortably above average. It is rated as highly volatile.

Cluster Tumble Symbols and Audio & Video Design

Relax Gaming has done an excellent job of bringing the Cluster Tumble online slot game to life. The action starts with a little video detailing the missing adventurer at the heart of the story, and we are then introduced to his wife. 

Her design is clearly inspired by Lara Croft only if she had spent some time in a tattoo parlour. She sits at the side of the reels throughout the game, swinging into action at various points as you move through bonuses and unlock features. 

The main symbols in the game are ancient artefacts, with a tiger mask being the most valuable, paying out 2,000x if you land a cluster of 40+, followed by a green bug and a blue mask, which both pay out 1000x each for the same number.

Cluster Tumble Mobile Features

Relax Gaming has developed the Cluster Tumble online slot to work across a range of operating systems and devices. The Cluster Tumble mobile slot is available on Android and iOS, and can also be accessed on mobile casino apps.

Cluster Tumble Bonus Features

The action keeps on coming in the Cluster Temple slot thanks to the following exciting bonus features.

Winning Modifiers

It is possible to unlock one of three mechanics from a stone whenever you land an adjacent win. The features are: 

  • Wild - Additional Wild symbols are revealed. 
  • Lightning Win - The block reveals a symbol. Any matching instances of that symbol are paid out as a combination, regardless of their position on the grid.
  • Fire Transform - A random symbol is selected and on the next cascade, two other symbols will transform into that symbol.

Free Spins 

You can unlock the Free Spins bonus by either revealing the entire grid or by landing three Scatter symbols. Either way, five spins are rewarded. During the round, if you clear the grid, you will get a 3x multiplier that is then applied to all wins. The grid does not reset between spins in the round, giving you more of a chance of stacking up wins and unlocking more spins.

Cluster Tumble Final Thoughts

Cluster Tumble is a great example of Relax Gaming firing on all cylinders. The game has an excellent story, a really fun design, and the central cluster and tumble-based gameplay mechanics work together really nicely. The Free Spins round is an excellent bonus, and if you unlock the grid and can get some nice sequences running, things can get pretty exciting. A maximum win of 20,000x your stake only sweetens the deal.
