Blobsters Clusterbuster™ replaces conventional paylines with cluster wins on a 9×9 grid. When a winning cluster disappears, symbols fall into its empty spaces and may form more wins, so one result can lead directly into another. A 3×3 spaceship sits over the grid’s centre; nearby cluster wins light it, building toward one of three progressing features.

Clusters feed a central spaceship
The game’s chain reactions refill spaces left by paid clusters with new symbols. This can create another cluster without requiring a fresh spin. The game page identifies the layout as 9×9 and win type as Cluster; it does not describe a payline count. Above the grid, Blobby’s saucer covers a 3×3 area in the middle.
The three features unlock in sequence: Upgrader, Frenzy and Supersize. After a feature has been unlocked, it may activate randomly on any spin. The central ship can therefore continue to matter after its initial progression: when activated after all three features are unlocked, it sends the game into Invader Spins.
Upgrader targets low-paying symbols outside winning clusters and turns them into higher-paying symbols, potentially completing clusters. It may upgrade 8–24 symbols in the main game and 11–31 during Invader Spins. Frenzy changes 5–20 randomly selected symbols into Wilds that substitute for all paying symbols.
Unlocks lead to Invader Spins
After all three features are unlocked, an activation of the saucer triggers ten Invader Spins. The feature begins on the same spin in which it is awarded, and the three progressing features trigger at an increased rate during the round. This ties the bonus to prior progression rather than a separate scatter trigger.
The feature interactions can compound through the grid. Upgrader may improve symbols outside existing wins and complete clusters; those clusters can clear and refill through chain reactions. Frenzy adds substituting Wilds, while Supersize enlarges selected high symbols or Wilds.
Configuration and trade-offs
The listed game has a 9×9 cluster grid, RTP of 95.70%, numeric volatility index 11.75 and maximum payout of 7,517x. No verbal volatility category is supplied. The release date is 9 February 2023. Stakes range from 0.10 to 50, and the configuration lists no Feature Buy. These values describe the standard game.
The strength is the way the central ship connects repeated cluster activity to a clear three-step feature ladder. Each feature changes the grid in a distinct way, and the transition into ten spins has a stated prerequisite. The limitation is that activation rates and several interactions remain unspecified.
Strengths and weak points
Strengths
The central UFO gives cluster play a longer-term target, and each unlocked feature changes the board through a different, clearly described symbol transformation.
Weaknesses
The source omits activation probabilities and the exact light threshold, while the lack of a listed Feature Buy makes the progression path difficult to quantify or bypass.
Our Editor’s View
Blobsters Clusterbuster ties its cluster grid to a concrete sequence: adjacent wins charge the central UFO, which unlocks Upgrader, Frenzy and Supersize before another activation starts ten Invader Spins. The feature effects alter symbol value, substitution and size, so the progression changes how the board can form clusters. This should suit players who enjoy evolving grid states; however, activation odds and the required light threshold are not specified, leaving the bonus pace difficult to judge.
