Cluster Tumble Review

A cool and fiery adventurer searching deep within tombs to recover the hidden treasure and rescue her husband - does this sound familiar? Inspired by Tomb Raider, Cluster Tumble is an adventure slot that plays on a grid of 8x8 and uses the Cluster Pays mechanic.

Developed by Relax Gaming, this slot comes as the fifth instalment in the Tumble series following Templar Tumble and Temple Tumble Megaways. Throughout this slot, you can trigger Free Spins with unlimited multipliers or even land one of the special symbols to increase your chances of winning big - so join our adventurer and see if you can survive the Himalayan Wilderness in Cluster Tumble.


It all starts with an opening cinematic that shows a newspaper story about the protagonist from Temple Tumble Megaways as he has gone missing. The newspaper states that his wife is on a mission to search for him and that's exactly where this slot starts. We see our heroine (unnamed sadly) climb a mountain and reach a gate. Overall, the visuals and music are already impressive at this moment with 3D graphics that look like a triple AAA videogame.

When the slot starts playing, you'll notice a gate surrounded by golden statues and skulls showing you that this is definitely somewhere that wanted to stay hidden. The visuals are stunning and definitely transport you into the journey. To the left of the reels, you get the heroine cheer you on and she reacts to certain spins which is entertaining to watch.

Once you've triggered free spins, you'll activate a cinematic that shows our heroine finding her husband and trying to rescue him. The background changes to inside the temple with gold surrounding the bottom and the hero from Temple Tumble Megaways hanging in a cage waiting to be saved.

The music for this slot is subtle as there's a soft beat of a drum mixed with a stringed instrument giving you an adventure feeling. It naturally gets more intense during free spins but stays within the tone of the slot.


As mentioned, this slot uses the Cluster Pays mechanic so you match up symbols of 5 or more to create a win. Once you do create a win, the reels cascade and drop in additional symbols. When this happens, you expand the grid and destroy blocks in the way. Ultimately, it's symbol gameplay that anyone can pick up and play.

In true Relax Gaming fashion, all the relevant buttons are at the bottom of the screen with the spin button in the middle. The bet level, autospin and additional settings can be found on the bar at the bottom.

Win Potential

Cluster Tumble is a high volatility slot that plays on a grid of 8x8. There is no set amount of paylines, so the possibilities are endless with unlimited multipliers during free spins. In terms of the RTP, it's a respectable 96.40% which is over the average standard.

Thankfully, you can win up to 20,000x your stake during the free spins round with multipliers. There are even two types of free spins, the regular free spins (medium volatility) and the high volatility - so you can decide on which one you prefer. There are two ways to trigger free spins (for non-UK players) as you can land 5 scatters or clear the board meaning it's quite accessible to trigger.

Our Verdict

The Tumble series has gone under the radar a little bit, but Cluster Tumble definitely puts it back on top form. Not only is the design spectacular, but the gameplay is enthralling and unlike any other slot.

We definitely want to see more of these characters and think they deserve their own unique series as they are entertaining to watch. On top of the impressive design and gameplay, the win potential is pretty solid with a decent maximum win and multiple avenues of how to get there.

Fans of Cluster Pays should definitely check out this slot as it's just so fun to play and Relax Gaming have definitely showcased something utterly brilliant. For a thrilling adventure, give Cluster Tumble a spin.
