What does John have to say?

Cluster Slide has a Reactoonz vibe, but it has plenty of its own fun and entertaining bonus features to have you grinning as you play.

Cluster Slide Slot Review

In true ELK Studios style, Cluster Slide is a fantastic looking slot that not only has lively animations and fun bonus features, but also a generous max potential. From the engaging fantasy theme to the slanting 8×7 cluster pays grid, nothing looks out of place here.

It’s just a shame that UK players can’t experience the X-iter feature that allows you to choose your favourite scenario. Anyhow, if you’re brave to face the monstrous beings, jump right into our slot review below to learn about their superpowers.

Cluster Slide Bonus Features

Cluster Slide is a funky online slot that has a lot of mini slot features and a solid bonus round.

The mini-features, set off by the generator, come in the form of wobbly monsters that can transform, expand, upgrade, boost and remove their fellow critters off the grid. The bonus round here magnifies the entire action, delivering even more wild effects with monstrous 3×3 symbols for bigger wins.

Much like the crazy Reactoonz, these monsters need a good spin to be fully understood, so let’s get started.


There are 6 wild-looking symbols living on the Jellyton planet, but only the pink one will substitute for all paying symbols except the bonus symbol and the other 5 jelly-textured Ws.


‘B’ is for bonus, and that’s what you’ll want to look out for in this extra fun Cluster Slide slot. If you land 3 of them anywhere on the cascading grid, they’ll activate the Wild Drops bonus feature.


There’s a ‘W’ counter meter in the top left corner of your grid. It fills up with every winning combination and awards one of five Feature Wild symbols, each with its own unique powers:

  • Big W – this one is a cannibal and expands a random symbol to a 2×2 symbol.
  • Random W – transforms 2-4 regular symbols into wilds.
  • Multiplier W – boosts your multiplier by 1x.
  • Upgrading W – chooses one random symbol type and upgrades all occurrences to a higher-paying one.
  • Removing W – chooses one symbol type and removes all its occurrences from the grid.

Plus, if you manage to land all 5 Feature Wild symbols in a single round, you’ll benefit from a 5x multiplier added to your wins.

Wild Drop Feature

Wild drops generate even more chaos on the reels. Triggered with 3 B symbols, the feature awards 3 Wild Drops with special effects. The first drop will turn all the bonus symbols into wilds and add three 1×1 wilds. The second drop adds two 2×2 jelly wilds while the third drop adds one 3×3 wild to your avalanche grid.

Cluster Slide Jackpot

Trust ELK studios to furnish their online slots with a generous max payout instead of a jackpot feature. The max you can win here is a very appealing 10,000x your stake.

RTP and Volatility

These squishy little monsters might look like a bunch of fun aliens, but they don’t award wins easily. Considering potentially good payouts, you’re right to expect medium-high volatility as well as a reputable RTP. The latter is set at 96%, which is in line with the industry standard.
