Tips & strategy
Aim to drop clusters, not just to pop three. Any bubbles left hanging with no connection to the ceiling fall away for free, so a single well-placed shot that severs a big group's only anchor can clear far more than the three you matched directly.
Use the walls deliberately. The straight-up shot is rarely the best one. Bouncing a bubble off a side wall lets you tuck it behind an overhang or reach a colour buried in a corner, and mastering these bank shots is what separates clearing boards from getting stuck.
Clear from the sides and work inward. Popping the edges first removes the anchors holding the middle in place, so central clusters drop away on their own. Digging straight up the centre leaves heavy shoulders on both sides with nothing to bring them down.
Watch your next bubble and plan two shots ahead. You can see the colour coming after the current one, so line up a spot for it as you take your present shot. Wasting a bubble because it had nowhere useful to go is how the ceiling catches up with you.
