Bubble Sorting

Sorting colored bubbles into matching tubes sounds straightforward — until it isn't. Bubble Sorting is a puzzle game built around that deceptive simplicity, where a single careless move can block an entire tube and unravel what looked like a clean solution. The satisfaction comes not from speed but from figuring out the right sequence, working backwards in your head before committing to anything.

Tubes fill from the bottom up, and no two different colors can sit adjacent, which means the order of every placement matters. When you hit a dead end, five undo moves give you room to backtrack without starting over completely — enough to correct a mistake, not enough to play carelessly.

Difficulty settings let you control how demanding the puzzles get, making it approachable whether you want a relaxed sorting session or something that genuinely makes you think twice before each move. The deeper you go, the more the puzzles reward patience over instinct.
