An inactive cluster of locked tiles is present on the reels. The outer tiles of the inactive cluster unlock when winning clusters are formed adjacent to it. Break all outer tiles to bust open the cluster and reveal its prize. The activated positions of the Clusterbuster™ reset on each spin.
Triggered when level 1 of the 3 progress circles is completed. Triggers randomly in future spins. Blobby will charge the UFO's weapons and shoot random low-paying symbols which are not part of a cluster to upgrade them to random high-paying symbols. Between 8 and 24 symbols may be upgraded in this way in the normal game and between 11 and 31 symbols in Invader Spins.
Triggered when level 2 of the 3 progress circles is completed. Triggers randomly in future spins. Blobby will charge the UFO's weapons and shoot random symbols on the screen transforming them into wilds. Between 5 and 20 symbols may be transformed into wilds in this way. Wilds substitute for all paying symbols.
Triggered when level 3 of the 3 progress circles is completed. Triggers randomly in future spins. Blobby will charge the UFO's weapons and shoot between 2 and 4 random high-paying or wild symbols on the screen making them grow to the size of a 3x3 Super Symbol.
Triggered each time Blobby's UFO is activated after all of the 3 other features have been unlocked. Each activation awards 10 Free Spins. Invader Spins trigger in the same spin in which they have been awarded. During Invader Spins the features trigger at an increased rate. During Invader Spins wilds may only appear from an activation of the Frenzy feature.
Blobby's UFO may be activated up to 3 times during Invader Spins. The first time this happens a x3 global wins multiplier is awarded. The second activation increases the multiplier to x7. The third and final activation increases it to x12. The multiplier resets at the end of the bonus round. Each activation also awards +3 bonus spins for a potential maximum of 19 Free Spins in total.
