Clear the chamber in 30 shots. Aim with the slider, mouse or touch, then Fire. Three or more connected bubbles of the same colour pop. Bubbles disconnected from the ceiling fall too.
Walls reflect your shot. The next bubble is shown beside the launcher, and only colours still on the board are supplied. Colours also have symbols so you can distinguish them without hue alone.
The gold dashed line is the danger line: a bubble reaching it loses the round. Running out of shots before clearing also loses. No new rows appear.
Remove a small group holding up a large cluster. Wall shots reach around obstacles. Check the next bubble before choosing where to attach the current one.
Arrow keys adjust the aim when the chamber has focus. Space fires and P pauses. Six starting rows, four colours, neighbouring colour patches. A new game regenerates the board.
