Every Extend Extra is a puzzle game where you're unable to shoot. The only way of defense is to detonate your "ship" in the vicinity of the enemy. Enemies appear in randomized patterns, and the main goal is to detonate at the right moment and position, to set up a chain reaction of explosions and earning a combo bonus. Blowing oneself up takes away from your overall stock of lives, with a new life being issued at specific amounts of points.
