In this beautiful thinking game, pop as many bubbles as you can over 20 levels by rotating the rings of bubbles to line up 3 or more! When they are ready to be popped the bubbles will be highlighted. You can only have 6 rings full, so anymore bubbles than that and its game over!
Click and drag on a bubble to rotate that ring. Click on the bubbles around the edge (or use the space bar) to bring more on quicker.
Mouse: to rotate a ring.
Space: to bring the bubbles around the edge.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
