Cluster Tumble is the 5th game in Relax Gaming’s Tumble series. This one takes you on an adventure to an Asian temple and lets you see what sorts of prizes it has hidden away. It legs you snag a couple of them too. You can think of this title as the provider’s way of paying homage to Lara Croft. The review will tell you all you need to know about the symbols, features, RTP rate as well as volatility.

Bonus Rounds & Free Spins

8.5 

The thing to remember about Cluster Tumble is that it comes with a cascading reels feature. This means whenever there’s a win, the winning symbols are removed from the reels and new ones take their place. This gives you a chance to land another and another winning combination. The feature stops when there are no more winning combinations.

Stone Blocks Features

There are 2 stone blocks that can trigger 1 of 2 features when they’re next to a winning cluster. These are the lightning and flame blocks. They trigger the following features:

  • Lightning Win – the lightning symbol is replaced by one of the standard symbols in the game. On the next cascade, all the targeted symbols form to make a win and they don’t need to be in a cluster to do so.
  • Fire Transform – the fire symbol is transformed into a targeted random symbol. On the following cascade, 1 or 2 symbol types will be transformed into this targeted symbol. So, you can expect a nice win.

Free Spins

To trigger the free spins you can unlock all the positions on the reels. The other way you can do so is to get a combination of 3 or more Scatters in a single spin. Regardless of how you trigger them, you get 5 free spins to play with.

Whenever a Scatter lands, you’ll get 1 more free spin which means you can get an infinite number of free spins. If you’ve unlocked all the spots on the reels, you’ll get a 3x multiplier along with 3 more free spins. If you do so again the value of the multiplier increases so you’ll get 6x, 9x, 12x, and bigger valued multipliers.
