Every bubble holds a picture. Which ones belong together?
Merge them, pop 4 of a kind and clear the jar.
Bubble Sort is a merge puzzle with a brain-teaser twist: the sorting happens in your head.
🫧 HOW TO PLAY
• Drag a bubble onto another bubble from the same group
• Collect 4 matching pictures in one bubble and it pops
• Clear the whole jar before you run out of moves
🧠 A SORT PUZZLE THAT M
AKES YOU THINK
Sweets, flowers and butterflies are easy. But "Floats on water"? "Fits in your pocket"? "It might bite"? Some
pictures could belong to several groups, and every wrong merge costs a move. Each level is a tiny riddle
about how things go together, so this picture puzzle trains your logic while you relax.
✨ FEEL THE SQUISH
Bubbles bounce, wobble and pile up with real physics. Grab one, drag it around and watch the others make
room. Every merge is a satisfying squish, every pop a little celebration.
♾ ENDLESS LEVELS
Levels are generated fresh, so no two puzzles are alike. Difficulty ramps up gently, with Hard and Extreme
challenges waiting every few levels. Stuck? The Lightbulb reveals a pair, the Magnet turns a bubble into the
picture you need, and Extra Bubbles give you more to work with.
