How to play
Aim the launcher and shoot a bubble up into the cluster. When it touches two or more bubbles of the same colour, the whole group of three or more pops. Bubbles left hanging with nothing linking them to the ceiling drop for bonus points. Bounce shots off the side walls to reach tricky spots. Every few shots the ceiling moves down one row — the dots at the bottom right show how many shots remain before it does. Clear the whole board to reach the next level. The game ends when bubbles cross the dashed line at the bottom.
Controls
With a mouse, point to aim and click to shoot. On a phone, drag to aim and lift your finger to shoot. Tap the small bubble on the left to swap your current bubble with the next one. On a keyboard, use the left and right arrow keys to aim, Space or the up arrow to shoot, and the down arrow or X to swap. Each colour also carries its own small symbol, so the colours are easy to tell apart.
Scoring and tips
Each popped bubble is worth 10 points, each dropped bubble 20, and every cleared board adds a level bonus. Go for bubbles that hold up big clusters: popping a few near the top can bring down dozens at once. Use the swap to save a colour for a better spot, and use the dotted guide to line up bank shots.
