Cluster Tumble Online Slot Review

Are you ready to rumble and tumble in clusters? Relax Gaming’s latest slot, Cluster Tumble, tries to take the Cluster Pays format to new heights. It’s a slot with 8 reels and thousands of tumbling winning opportunities in an adventure setting on the outskirts of Nepal.

You’ll be taking the role of a brave explorer out there to save her husband. During the dangerous adventure, you’ll encounter plenty of obstacles in your way and overcome them in different ways while scoring great payouts at the same time.

The Cluster Tumble slot also pays great attention to the storytelling. There’s an intro on the events that lead to the game, and we’re glad Relax Gaming has taken all this effort – it just makes the slot more exciting.

You can play the Cluster Tumble slot in any Relax Gaming top online casino for free and real money or with a bonus.

Cluster Tumble Slot Setup and Paytable

From the moment you lay eyes on it, it’s clear that Cluster Tumble isn’t your regular online slot. It’s got an 8x8 layout, but many of the blocks are greyed out – those areas are not playable right away. What is playable is the cluster in the middle of the grid with various symbol formations.

The adventure theme means that the slot is set in some kind of a temple on the outskirts of Nepal. You’ll see two heavily ornamented columns on both sides. When it comes to the symbols, the slot uses various totem-style figures that pay the most for clusters of over 40 (up to 2,000x your stake).

There are special blocks too, showing Wilds, Lightning Win, and Fire Transform.

Cluster Tumble Slot Gameplay

To start this dangerous Nepalese adventure, you’ll have to place a bet. Your options range between $0.10 and $50 per spin. Choose what suits you best and hit the Spin button to start.

The main feature in the base game is the Tumbling mechanic. This is a Cascading feature on each win that can continue as long as there are winning combinations. It comes with a twist in the Cluster Tumble slot, with each win cracking new playing areas open.

Some stone blocks contain special features that are activated when they are destroyed. The Wild plays its usual role, while Lightning Wins targets random symbols and transforms them into a matching one. Fire Transform is the last block symbol that will transform 1-2 symbols to matching ones for the following cascade. It works similarly to the Lightning Wins mechanic but on a smaller scale.

Cluster Tumble Slot Free Spins

Land 3 Scatters or remove all stone blocks in the main game, and you’ll get entry to the Free Spins Round. It starts with 5 free games with 3 extra spins if you manage to clear the whole board. At the same time, this also raises the Multiplier by +3, with every next grid clear raising it by +6, +9, etc.

The increasing Multiplier is persistent throughout the round. Any Scatter that lands on the reels gives you an extra spin. If you don’t want to wait for the Free Spins Round, you can use the Buy Bonus feature. It costs 100x for the regular Free Spins Round and 200x for volatile free spins with higher starting Multipliers.

Cluster Tumble Slot RTP and Max Payout

Cluster Tumble Slot Verdict

Cluster Tumble is a dangerous and exciting adventure from Relax Gaming that explorers wouldn’t want to miss. It’s got a bit of Tomb Raider vibe, and that’s OK with us. Clearing the grid by destroying the blockers is quite rewarding and exciting, especially if you hit Lightning Win or Fire Transform symbols.

Hit clusters of more than 40 matching symbols, and that’s where the slot blooms. With a bit of luck on your side and the right blocks removed, you can win up to 20,000x your stake. That’s a pretty satisfying real money slot reward for most players.
