About Blobsters Clusterbuster Slot 

Blobsters Clusterbuster slot by Red Tiger Gaming features a galactic setting with rewarding aliens. This slot has a Cluster Pay mechanic, which doesn’t include typical paylines going from left to right. 

The Blobsters Clusterbuster slot has a large 9x9 gaming grid, with a 3x3 chunk in the middle. This 3x3 chunk is the so-called Clusterbuster, which is some form of a UFO. The minimum bet is 0.10p, while the maximum bet is £10 per spin, which is great for casual players but not as much for high rollers.

The goal in this slot is to land at least five matching symbols in a cluster - adjacent horizontally or vertically. Blobsters Clusterbuster slot has three locked modifier extras in the middle, which could trigger features, which I will explain more about below in this review. 

Design, Symbols, and Graphics

The game design is exciting and a lovely refreshment from regular video slots. I liked the sizeable 9x9 grid with the Clusterbuster in the centre. 

The graphics are sharp, and the visuals consist of a scene with stars, planets, and cosmic gas. The sounds are also attractive when you hit play, providing excellent and immersive gameplay. 

Like most other video slots, the low-paying symbols involve card royals between J and A. The top-paying symbols are blue, green, pink, and yellow aliens. As the most valuable symbol, the yellow alien is worth up to 250x the stake for a cluster of 95 symbols or more.

Technically, there are no special symbols in the Blobsters Clusterbuster slot, so the bonus features can all be triggered through the Clusterbuster in the middle. I will explain this all in more detail later.

RTP, Variance, and Payouts for Blobsters Clusterbuster Slot

The Blobsters Clusterbuster RTP is 95.70%, slightly below the industry average. The game’s high volatility may lead to scarce but more valuable rewards, while the maximum possible payout can reach up to 7,517x the bet.

Gameplay and Features on Blobsters Clusterbuster Slot

The game’s gameplay can keep players entertained through its exciting features. As mentioned, there are three locked modifier extras when you start the slot, meaning you must unlock them before triggering any feature. Let’s explore the details now.


The adjacent lights will turn green when a winning cluster happens next to the 3x3 Clusterbuster UFO in the middle of the grid. When all UFO lights turn green, you will unlock a feature. 

Once this happens, Blobby, the alien in the UFO, will activate one of them on the next spin. Then all lights will go off, ready to light up again on future spins with the same bet. 

Also, with unlocked features, you can randomly trigger them on future spins. It does not have to be a single feature, but you can initiate more than one within the same spin. The three modifier features in the Blobsters Clusterbuster slot are:

  • Upgrader - Blobby, the alien, will shoot random low-paying symbols, transforming them into random higher-paying aliens; 
  • Frenzy - Blobby will shoot up to 20 symbols, turning them into Wilds;
  • Supersize - Blobby shoots between two and four random higher-paying symbols, enlarging them to 3x3 Super Symbols, each worth the same as nine regular symbols. 

Invader Free Spins

After players unlock the three modifiers, from then onwards, whenever you activate eight lights on the UFO, you will trigger the Free Spins feature, awarding 10 spins. During the free spins feature, modifiers can be more frequent.

Theoretically, you can activate the UFO in the middle up to three times during the free spins round, with each activation awarding three additional free spins. Also, the first, second, and third activation will add x3, x7, and x12 multipliers in the Invader Free Spins feature.

Our Verdict 

Red Tiger Gaming did an excellent job with this cluster pay slot, considering it is the third time they are utilising this mechanic. When it comes to Blobsters Clusterbuster, the gameplay thrilled me as I was chasing to unlock features. Modifiers and multipliers are excellent, with up to a 7,517x winning potential.

The game symbols and unlockable features are the best assets of this game, with Super Symbols being the most exciting for me. It is a great game to entertain yourself, so give it a shot, and good luck spinning!
