Cluster Slide Slot RTP, Details & Wager Limits

As you might guess from its name, the Cluster Slide slot uses a Cluster Pays game engine. Played on a 7×8 grid, winners are created by landing clusters of 5 or more matching symbols. After a winning cluster is formed, those symbols are removed. Instead of dropping in from above, the new symbols slide onto the grid from the right. A new payout consideration is then made. Slides keep on coming until no new winning cluster is created.

You can play Cluster Slide at stake levels of between 20p and £100 per spin. Click on the coins in the bottom left-hand corner of the screen and choose from 12 different stake options.

The Cluster Slide RTP is 96% with the variance in the high category. The bigger wins will come from the multipliers and feature wilds. The maximum win comes in at 10,000 x your total stake.

Theme – Audio & Design Features – join cartoon critters on planet Jellyton

cluster-slide-slot-base-game

The rocky surface of the mysterious planet of Jellyton is the setting for the Cluster Slide slot. With an outer space theme, the cartoon-style design is bright, colourful and simply done. It works rather well. As does the soundtrack. It doesn’t have much of a sci-fi feel to it but it bounces along nicely enough.

The 7 reel, 8 row game grid is made up of a 4 gemstone-style symbols and 4 high value hairy critters. There are quite friendly and not as scary as the ones from the 1986 Critters film. The best of them is the red critter with the crown and moustache. Land 5 of him in a cluster for a payout of 1 x your total stake. Land 15 or more in a cluster and he delivers an award of 500 x your total stake.

Remember, it’s possible to boost these numbers with multipliers which I’ll look at below. There are also wilds, feature wilds and a bonus symbol.

You can play Cluster Slide on mobiles and tablets as well as desktop computers. With 56 symbols on the game grid, the design here needs to be good. Thankfully, the bright symbols against the dark backdrop work just fine when you’re playing on a device with a small screen. The gameplay is certainly unusual, but the Cluster Slide mobile slot is perfectly clear.

Cluster Slide Bonus Features

In this space adventure, wilds are central to much of the best action. Fill the Feature Generator to activate these wild modifiers. There’s also a Bonus Games feature that awards free spins with even more wild extras.

Feature Generator

cluster-slide-slot-feature-generator

Whenever you land a winning cluster, the winning symbols contribute to the Feature Generator which you can see in the top left-hand corner of the screen. Once the Generator is full, you’ll receive a Feature Wild. There are 5 features in all:

  • Big Wild feature: this is a 2×2 wild symbol.
  • Random Wild feature: between 2 and 4 random positions on the reels turn wild.
  • Multiplier Wild feature: this increases a multiplier by 1x.
  • Upgrading Wild feature: this turns all examples of a symbol into a higher paying symbol.
  • Removing Wild feature: all examples of a symbol are removed from the game grid.

The feature wild extra triggers when they make up part of a winning combination.

Multiplier feature

If you manage to land all 5 Feature Wilds in a single game round, you’ll trigger the Multiplier feature and bring a 5x multiplier into play. It’s possible to add to this multiplier too and trigger even larger payout boosts. The multiplier resets to 1x following a drop where no new winning cluster is formed.

Bonus Game feature

cluster-slide-slot-bonus-game-feature

Land 3 Bonus symbols on the same spin and you’ll trigger the Bonus Game feature. Your reward is 3 Free Wild Drops or free spins. On the first drop, the triggering Bonus symbols turn wild and they’re joined by 3 1×1 wilds which are added to random positions on the grid.

On the second free drop, a pair of 2×2 wilds are added to the reels. Helping your winning chances is a colossal 3×3 wild on the third and final free drop.

X-iter feature

In some territories, you’ll be able to activate the X-iter feature. This allows you to play in a variety of game modes which offer a series of extras. These include symbol drops with multipliers, collected symbols and wilds which return on the final spin, a trigger of the Bonus Game feature or the Bonus Game feature with wild extras. The price of these extras ranges from between 15 and 300 x your total stake.

Cluster Slide Review Summary – unusual gameplay makes this planet worth exploring

ELK Studios has taken a variety of familiar elements (space theme, cluster pays, sliding symbols) and shaken them up to create something innovative and fresh in the Cluster Slide slot.

The feature wilds can deliver some top action. It can take a while to fill the Generator but a good run when they do arrive can be worth waiting for. The Multiplier Wild feature is particularly good especially is combined with the Multiplier feature. Likewise, the Bonus Game feature where the oversize wilds can really get things moving.

The game engine is slightly unusual so a few spins in demo mode are recommended if you can. If you like the space theme but fancy some rather unusual gameplay, that’s just what’s on offer in Cluster Slide.

If you want cluster pays slots, the 2 best ones are Jammin’ Jars by Push Gaming and Sweet Bonanza by Pragmatic Play.
