Cluster Slide Online Slot Review

Play the Cluster Slide slot online to discover a selection of friendly alien creatures across a 7×8 grid of colorful symbols. The game title describes a win mechanism where clusters of symbols pay prizes before vanishing, and remaining symbols slide to the left as new ones drop from above.

Special wilds expand symbols, increase win multipliers, upgrade symbols, or perform other tricks, while giant wilds appear during a free games feature of the Cluster Slide online slot. This desktop and mobile game features a medium to high volatility and average paybacks of 96%.

Enter the Aliens’ World

The big grid of bright symbols rests on the surface of a far-off planet. Mountains rise up to either side, while red, green, and blue moons orbit this strange world. The symbols are no less alien in appearance, with glowing green, purple, orange, and red egg-shaped icons paying out smaller prizes. You win more from shaggy ‘mustache’ symbols in the same colors, with cartoon eyes appearing each time any of these become part of a winning cluster.

A strange mix of electronic beeps, laser-zaps, and other noises make up the energetic soundtrack. It comes from ELK Studios, and we’re sure the artists had a lot of fun designing the environment, creatures, and sounds. As far as online slots themed around outer space go, this is certainly one of the more unusual ones. The gameplay and features of the Cluster Slide slot machine are just as out of this world.

Choose Your Stakes

Bet options run from 0.20 to 100.00 on each spin. There’s an Autoplay mode but no fast-spin feature, which is fine, as the gameplay of the Cluster Slide online slot is already pretty quick. Under the cluster pays system, you need to land groups of five or more matched symbols to win, with greater prizes paid out for larger clusters. 

This paylines table shows you how many times your bet each symbol is worth, for the minimum clusters of five, and a maximum of 15+.

The Cluster Slide slot machine features ELK Studios’ X-iter bonus buy system. For an extra cost, you can guarantee bonus symbols, enter free the games feature, collect multipliers, or trigger free drops. We found a medium to high volatility here, and it comes with an average payback percentage of 96%.

Slide to the Left

A Sliding Avalanche feature removes winning symbols, and those that remain slide to the left side of the grid, following the tilt of the reels. If this creates a new winning cluster, you get further avalanches and slides, with a meter above the reels filling with each in a sequence. 

Winning alien mustache symbols come alive as an eye appears. Further animations zap energy from the wins into a Wild Generator meter at the top of the Cluster Slide online slot reels. There are five different wild modifiers, and the meter displays the red, blue, green, purple, or multicolor wild at random. If you fill the meter with winnIng symbols in a series of avalanches, the following wilds return to the reels –

• The red Big wild expands a random symbol to 2×2 size. 
• The purple Multiplier boosts a win by 1x.
• The blue Upgrading wild turns all examples of a random symbol into a higher value one.
• The green Removing wild clears a random symbol from the reels to trigger an avalanche.
• The multicolor Random symbol places between two and four extra wilds onto the grid.

Build Multipliers & Claim Free Drops

If all five wild modifiers trigger during a series of avalanches, an extra 5x multiplier applies on top of any created by the purple wild. There’s also a standard blue and pink wild symbol that appears at any time.

Land three or more ‘B’ bonus symbols, and you get three free Wild Drops. These are essentially free spins of the Cluster Slide slot machine, where your chances of winning get a big boost from further wild symbols. The triggering bonus symbols turn into wilds in the first drop, while two 2×2 wilds appear in the second. On the last spin, a huge 3×3 wild appears, and these all trigger avalanches. 

Encounter Some More Strange Creatures

The Reactoonz 2 slot machine from Play’n GO stars a collection of aliens across a 7×7 grid. It’s another cluster pays game with avalanches on each win. Fill meters to release giant wild Reactoonz onto the reels. 

If you like the looks, but prefer a conventional reel layout, be sure to play the So Many Monsters slot from Microgaming. This five-reel, 25-line game sees cute cartoon monsters split into between two and five examples of the same type, potentially giving you 25 matched symbols on a line.

Explore a World of Cartoon Aliens

The bright colors and strange landscape will certainly grab your attention, while the fast gameplay and multiple features keep the thills coming in every avalanche. It’s an unusual game, so play Cluster Slide slot for free right here to get a feel for the bonuses. It’s a great way to experience the fun animations and winning potential without even needing to leave this site.

Then, unleash the aliens in this hugely entertaining slot at the top ELK Studios online casinos featured here at VegasSlotsOnline.
