Cluster Tumble Review

Relax Gaming has churned out a decent number of online slots with the word ‘Tumble’ in the title by now, but they are not really all that related most of the time - at least not thematically. Cluster Tumble clearly follows in the footsteps of their successful Temple Tumble Megaways however, and the impressive cinematic intro reveals that the Husband Explorer from the previous release has gone missing.

His equally world-renowned Explorer Wife (we really could use a name for these characters by now) is on the trail however, and perhaps this is how they keep the excitement going in their marriage. Anyway, you can look forward to unusually lengthy and highly satisfying exploding cascades in this release, and these remove stone blockers that sometimes come with modifier action. Payouts up to 20,000x your stake is possible via the unlimited +3 incrementing bonus round multiplier, but clearing the grid to increase it is not always an easy task.

Cluster Tumble Slot Features

Wilds can land anywhere on the grid, and they step in for regular pay symbols to help complete winning clusters. Wilds come with up to 5 lives, and the tally decreases by 1 life every time the wild is used in a win. Between 4 and 40 matching symbols in a cluster anywhere on the grid is what pays, and 40+ award payouts of 50, 100 or 2,000 x your stake.

The Cascading Wins mechanic works a bit differently than you might be used to. Not only are winning symbols removed, but all adjacent symbols as well.

Some of the stone blocker tiles come with icons indicating their modifier abilities, and these become active if adjacent to a winning symbol:

• Wild - generate wild symbols (with or without countdown lives).
• Lightning Win - turns into a random pay symbol, and all matching symbols in view generate a win no matter where the symbols are located.
• Fire Transform - also turns into a random pay symbol, and 1 or 2 symbol types are then turned into the same symbol in the cascade that follows.

The Bonus Round is triggered when you either clear all the stone block symbols from the grid, or you land 3 scatters anywhere in view in the same cascading sequence. You get 5 free spins either way, and clearing all the stone blocks during the feature awards an x3 win multiplier. The multiplier increases indefinitely by +3 every time you clear the grid, and scatters that land award +1 extra spin.

Non-UK players can take advantage of the Bonus Buy feature, and it comes with 2 options. The default version costs 100x your stake, and it gives you 5 free spins. There is also an extra volatile option that costs 200x your stake, and the difference is that the multiplier increases by +6 per cleared grid instead of +3.

Review Summary

The cinematic story adds a charming and romantic frame to the gameplay, but it’s a bit over the top with the Bambi-eyed husband and all. That’s a minor detail however, and Cluster Tumble is bound to suck you right into the action when you see the chainreaction fireworks of exploding tiles that a single win can set off. Having the right “gravity setting” and pace is alpha and omega in a game with so many lengthy cascading sequences, and Relax Gaming totally nails it in that department.

The gameplay is highly satisfying and immersive in all stages, but keep in mind that you will most likely need bonus round multiplier action to truly make a dent. Clearing a 64-tiles grid is far from easy though, especially since you’ll usually start with only 10-20 symbols surrounded by stone blockers. Many times you’ll get a single larger win (if even that), while the remaining free spins award little to nothing. Up to 20,000x is possible on a good day though, and overall this is a highly engaging thrill-ride grid slot fans don’t wanna miss.

Pros

• Cascades destroy winning + adjacent symbols/blockers
• Stone blockers can come with 3 unique modifiers
• FS w/ unlimited cleared-grid multiplier that increases by +3
• Volatile FS buy option w/ +6 incrementing multiplier (not UK)
• Solid 96.4 % RTP (and not customizable!)
• Win up to 20,000x your stake

Cons

• Cinematic love story is a bit too cheesy
• The explorer husband and wife could use a name

If you love Cluster Tumble Slot you should also try:

Temple Tumble Megaways - is a Relax Gaming prequel where the explorer husband that’s missing in this game serves as the wild symbol. The stone symbols are blocking the entrance to a temple also here, and removing them all is how you trigger the bonus round.

3 Secret Cities - follows a female explorer who discovers new Aztec cities in the mesoamerican jungle via the scatter pick game, and this is also how you upgrade to the next bonus round via the ‘bonus up’ system. All 3 of them come with a progressive win multiplier, a super stacked symbol and the top-tier FS round can land you 50,000x your stake.

Lara Croft Temples and Tombs - is based around the female adventurer that all others are inspired by, and this Triple Edge Studios release comes with a rolling reels win multiplier that can lead to solid base game payouts. The multiplier is increased up to x15 at the most in the bonus round, and while the overall max win is 7,343x your stake, there are also 3 fixed jackpots up to 5,000x.
