How to Play Blobsters Clusterbuster

The Blobsters are a friendly bunch—blue, yellow, pink, and green aliens with goofy grins and varying numbers of eyes. Card suit symbols fill the low-paying positions, while a large grey-blue alien in his UFO sits at the grid’s center. The action unfolds against a cosmic backdrop with quirky sound effects.

• Devices: Play on PC, iOS, Android, or Windows mobiles.
• Bet range: 0.10 – 100.00 per spin.
• Payouts: Clusters of 5+ matching symbols pay, with the yellow alien worth up to 250x your stake.
• Controls: Stake selector, Pays button, Turbo (where available), and Auto Play (not for UK players).

Clusterbuster Free Spins & Bonus Features

Every win triggers cascades, removing winning clusters so new symbols drop down. The UFO in the center is key: adjacent winning clusters light up the 8 surrounding lamps, which unlock modifiers in sequence:

• Upgrader: 8–24 card symbols transform into higher-paying aliens.
• Frenzy: 5–20 symbols randomly turn into wilds.
• SuperSize: 2–4 symbols expand into 3x3 blocks, counting as clusters of 9.

Once unlocked, modifiers can appear randomly for the rest of your session (provided your stake level doesn’t change). After all three unlock, lighting up the UFO launches the Invader Spins feature: 10 free spins with more frequent modifiers and multipliers of 3x, 7x, and 12x added when the lights cycle three times. Each stage also adds 3 extra spins.
