The playfield is viewed from the side. Colored bubbles hang from the ceiling, and the player controls a launcher at the bottom, aiming shots around walls or into open gaps.

Attach a fired bubble to two or more bubbles of the same color to make a group of three or more disappear. Unsupported bubbles may fall as well. Stages become harder through more complicated formations, limited space, and increasing pressure from the ceiling. The objective is to clear each arrangement before the bubbles reach the danger line.

Aim for groups that support large sections of the ceiling rather than only making isolated matches. Removing a supporting cluster can drop many bubbles at once and conserve shots.

Use wall bounces to reach enclosed spaces, and watch the next bubble before committing to a difficult angle. Prioritize shots that prevent the formation from descending into the danger area.
