Cluster Tumble Slot

Our rating:
  • A fun cluster slot with lots of features
  • Special blocks with unique modifiers
  • Free spins help you build up big multipliers

Cluster Tumble slot is a new cluster game from Relax Gaming with a big focus on multipliers that are available during the free spins bonus and this is how you can achieve the impressive 20,000x win potential. Combined with an RTP of 96.4%, this is really quite impressive. But before we look at the features in detail, let’s talk basics.

You’re greeted first with a stunning intro and the graphics as a whole in this slot are some of the best I’ve ever seen. You have a large 8×8 grid and you need to spin the reels to try and get a cluster of symbols that are as follows, ranked in ascending order based on their value:

  • Blue, Green or Red Jewel
  • Blue Mask or Green Scarab
  • Dragon

There is also a wild symbol, substituting for all others on the reel. These can have up to 5 lives on them, decreasing whenever they are used in a win.

Cluster Tumble Slot Bonuses and Features

Stone Blocks. Sometimes a stone block has a special feature. These are as follows:

  • Wilds. Some stone blocks are wild symbols, substituting for all others in a win.
  • Lightning Win. When this one is activated, it’s replaced by a regular symbol and all normal symbols of the same type in the next cascade form a win, regardless of their position.
  • Fire Transform. This block will also be replaced by a regular symbol, and 1-2 symbols will turn into the same kind.

Free Spins Bonus. This is triggered when you land 3 scatters anywhere on the board, or when you removed all stone blocks. You’ll be given 5 free spins, and clearing the board during the bonus gives you another 3 free spins as well as increasing your multiplier by 3x. Additionally, you can land scatters during the bonus, giving you 1 extra free spin each.

Bonus Buy. Outside of the UK, you can buy the bonus for a rather costly 200x your stake. However, in return for the high buying price, multipliers increase twice as face as normal, in increments of 6x instead of 3x.

Cluster Tumble slot from Relax Gaming is certainly one of the most beautifully designed slots I’ve ever seen. The intro at the beginning is fairly short but the graphics are stunning, and this carries on to the main game. In the base game you have a few, fairly simple features involving extra wilds or transforming other symbols to get you extra wins. Clear the screen of blocks or land 3 scatters and you’ll get the free spins bonus where your multipliers can increase substantially. It’s a shame the bonus buy isn’t available here, as multipliers increase twice as much so you can really expect big rewards from that. Overall, I like it a lot though without the bonus buy option it is quite a bit harder to achieve that 20,000x potential.
