How to win big in Cluster Tumble – Free Spins feature

How to win big in Cluster Tumble – Free Spins feature

You are able to trigger the Free Spins feature in two different ways. You can either land 3 or more scatters anywhere on the reel set during a spin or unlock all the symbol positions. Whichever way you trigger the free spins feature, you will be rewarded with a total of 5 free spins. During the feature, you will be rewarded with one extra free spin for every scatter landing on the reel set, which potentially could result in unlimited free spins.

Should you manage to unlock all the stone blocks on the game grid, you will be receiving a multiplier boost. The first time you manage this, you will activate an x3 multiplier while also receiving 3 more free spins. If you should do it again, then the multipliers will increase by 3, 6, 9, 12 or more. Once you have an active multiplier in the free spins feature, it will remain at the same level or be increased, it will never reset to x1 until you return to the main game.

Special Features

Special Features Cluster Tumble

  • Cascading Wins
  • Special Stone Block
  • Feature Buy

In this slot, you will be seeing a Cascading Wins feature which is triggered when you land a winning cluster of 4 or more matching symbols. Any adjacent positions will become unblocked and new symbols are added. The explosions will keep on happening as long as new or improved winning clusters are being made. Should you manage to unblock all the 64 positions on the grid, then you will activate the Free Spins feature as mentioned above.

Then you have the Special Stone Block feature, which actually consists of two different features and becomes active when you have a winning combination directly adjacent to them.

Lightning Win feature - will be replaced by a target symbol. This target could be any of the standard symbols. A cascade will then follow where all examples of the target symbol will be combined in order to form a winning cluster where any combination of 4 or more of them anywhere on the reels will get you a win.

Fire Transform feature – again, the Fire Transform symbol will be replaced by a target symbol, which can be any standard symbol. During the next cascade, 1 or 2 symbol types will transform so they are able to match the target symbol. A new payout consideration will then follow, as the newly transformed symbols are in place.

Finally, you have the Feature Buy option where you will be able to buy your way into the Free Spins feature. This will set you back x100 your total stake. You can also buy your way into the volatile free spins where the cost will be x200 your total stake.

Look and Feel of Cluster Tumble

Look and Feel of Cluster Tumble

The design and look of Cluster Tumble is like a mash-up of the Tomb Raider movies and Indiana Jones movies. Relax Gaming has done a great job with the design, where you will find yourself in the Himalayas where the adventurer has gone missing. The background shows a citadel, as you will be seeing stone walls while the reel set itself has been set between two totem columns, the totems appearing to be made out of gold. Sound effects such as explosions when there are winning clusters along with the adventurous soundtrack also add to the atmosphere of the game.

Cluster Tumble Paytable

On the reels, you will see that the low-value symbols are represented by different gemstones, made up of blue, green and red ones. The high-value symbols on the other hand are represented by different items such as a green scarab beetle, a blue Aztec chief and a pink dragon who also happens to be the highest valued symbol.
