Blobsters Clusterbuster Slot Review

Blobsters Clusterbuster is the third online slot game released by Red Tiger Gaming to use the titular Clusterbuster mechanic. The idea of the mechanic is simple – a 3x3 portion of the grid is locked off, and players need to land winning combinations around it to ‘bust’ it and trigger bonuses. This Clusterbusters slot takes us shooting off into space, where we encounter a group of little aliens that look as though they could have crawled straight from the reels of the Reactoonz slot. Does this slot continue the trend of fun Clusterbuster action? Let’s take a look and find out.

Blobsters Clusterbuster Slot Game Design

Red Tiger never cuts corners with its game designs, and Blobsters Clusterbuster is a testament to this. The slot has an out-there design, with a selection of little alien creatures filling its enhanced game grid. The reels are floating in outer space, with some nifty animations bringing the background to life. The centre of the reels looks brilliant, with a little blue alien wearing a tiny crown bursting out of the screen at you. There are plenty of alien-themed slots on the market, including big hits like Reactoonz, and from a visual perspective, Blobsters Clusterbuster is up there with the best of them.

How to Play Blobsters Clusterbuster Slot

As previously mentioned in this Blobsters Clusterbuster review, the game uses an enhanced reel set to play host to its action. The slot uses a 9x9 grid and a Cluster Pays mechanic. This means wins are paid out for clusters of five or more landing anywhere on the reels.

Like most top real cash slots that use Cluster Pays, the game has an Avalanche wins mechanic. Whenever a winning cluster is formed, it disappears from the grid, and more symbols fall onto the reels. This continues until no winning clusters are formed.

The stake is adjusted by clicking the stake button in the bottom left-hand corner of the grid. The minimum stake in the game is £0.20, and the maximum is £10. This small range will only appeal to players on smaller budgets.

Playing Blobsters Clusterbuster Mobile Slot

These little alien critters have no problem jumping to the smaller screen. The Blobsters Clusterbuster mobile slot plays in the same way as the desktop version, with players being able to trigger the same features and win the same potential prizes.

Blobsters Clusterbuster Slot Bonus Features

The titular Clusterbuster refers to a giant 3x3 UFO symbol sitting in the middle of the screen. The aim of the game is to trigger the lights around this by landing winning clusters around it on consecutive spins. You can also unlock three different reel modifiers by landing clusters around the symbol and fillings the eight lights around the UFO.

The modifiers are released sequentially, and once activated, they can trigger on any random spin. These are modifiers in order:

  • Upgrader: Low-paying symbols not part of winning clusters are transformed into higher-paying symbols.
  • Frenzy: Up to 20 symbols can be shot at by the alien and turned into Wilds.
  • Supersize: High-paying symbols can be randomly shot at, transforming them into giant 3x3 Super Symbols.

Once you have unlocked all of the modifiers, you will next unlock the Invader Spins. Players are given ten spins, with the modifiers activated much more regularly. You can also retrigger the spin, which each retrigger adding a global multiplier to the grid. The maximum multiplier is 12x.

Blobsters Clusterbuster Slot Summary
