About Plopfuse

Plopfuse is a drop-and-merge puzzle with soft physics. Each bubble you release falls, rolls and settles against the others; when two bubbles of the same tier touch, they pop together into one larger bubble of the next tier. The glass is narrow, so sorting matters more than speed: keep small bubbles on one side, big ones on the other, and leave a lane for the giant merges. There are eleven tiers from a tiny fizz bubble to the party bubble, and reaching the last one is a genuine achievement.

How to play

Drag left or right to position Prof. Plop above the glass, then release to drop the bubble. On a keyboard use the arrows and Space.
When two bubbles of the same tier touch they merge into one bubble of the next tier. Bigger tiers score more.
The next bubble is shown in the corner. Plan where it should land.
If bubbles rest above the dashed line for a few seconds the glass overflows and the game ends.

Tips

Keep big bubbles in the corners and small bubbles in the middle so new merges have room to roll.
Drop a bubble slightly off-centre on top of its twin so the merge pushes outward instead of upward.
The dashed line only counts when a bubble is resting on it, so a bubble bouncing past it is fine.
If the glass is getting crowded, chain small merges to lower the pile before dropping a big tier.
