The husband is missing, and it's up to you to find him. Cluster Tumble by Relax Gaming (released Nov 2021) is the fifth installment in the Tumble series, following the success of Temple Tumble. This time, we are in the Himalayas with a brave female explorer.

Game Overview & Specs
The 20,000x Max Win is standard for the Tumble series but still very high. The RTP of 96.40% is solid. The hit frequency of 20% means you might have some dead spins, but the wins tend to be significant when they chain together. The Red Dragon symbol is a beast, paying 2,000x on its own for a full screen.

RTP Analysis & Volatility Profile
Cluster Tumble is a game of momentum. You need a small win to break the first layer of rocks, which reveals more symbols, which creates more wins. If you fail to break the rocks, the spin ends quickly. The Special Blocks are crucial for keeping the chain reaction alive.

My 100 Spins Test Run
I played at €1.00 per spin.

- Spin 95: Cleared the board! Free Spins triggered.
- Spin 1: Cleared the board again! Multiplier x3. +3 Spins.

Verdict: Clearing the board feels like an achievement every time. The increasing multiplier in Free Spins turns a good run into a legendary one.
Where to Play: Mobile & Desktop
The 8x8 grid is dense, but the Cluster mechanic makes it easy to follow on mobile. The "Big Win" animations are satisfyingly explosive.
How to Play: Clear the Path
Set Your Bet
Bets range from €0.10 to €50.00.
Cluster Pays
Match 4+ symbols adjacently (horizontally or vertically) to win.
Tumble Mechanic
Winning symbols explode, and adjacent stone blocks are destroyed. New symbols fall in.
Unlock the Grid
The goal is to destroy all stone blocks on the board. Doing so in the base game triggers Free Spins.

Some stones contain power-ups (Wild, Lightning, Fire). Destroy them to activate the feature.
Free Spins
Triggered by clearing the board OR landing 3 Scatters.
Final Verdict
Cluster Tumble successfully reinvents the Tumble formula. It feels different enough from Temple Tumble to stand on its own. The combination of grid clearing strategy and high-payout symbols makes it one of the most engaging grid slots on the market.
Best For: Fans of grid slots and adventure themes.

FAQ - Frequently Asked Questions
How do I trigger Free Spins?
There are two ways: land 3 Scatter symbols anywhere on the grid, OR destroy all stone blocks on the board in a single spin.
What is the Volatile Free Spins option?
If you use the Bonus Buy, you can choose a "Volatile" option where the multiplier increases by x6 instead of x3, but you start with no multiplier. This is for high-risk players.
Does the multiplier reset?
In the base game, yes. In the Free Spins, the multiplier never resets; it only grows every time you clear the board.
What does the Lightning Block do?
It targets a symbol type and transforms regular symbols into that target symbol, ensuring a win. It acts as a great connector for clusters.
Is the 20,000x win capped?
Yes. If the total win of a round reaches 20,000x your bet, the game round ends immediately and the cap is awarded.
What is the minimum cluster size?
You need at least 4 matching symbols connecting horizontally or vertically to form a winning cluster.
