Bubble Sort

Transparent bubbles drift through the underwater world, holding little toys and ripe fruit. Scattered across the screen are a black-and-white penguin, an orange tiger with stripes, a purple octopus, and a gray hippopotamus. Nearby float a green alien with big eyes, garden flowers, forest vegetables, and garden fruit inside round homes. In Bubble Sort, group matching images to reunite these mixed-up residents and put the sea back in order.

How to play?

Tap a bubble to move it and rearrange the set. Bring identical pictures together until they combine into one bubble, then vanish. New sets appear as you progress. The top panel shows how many attempts remain, and each round gives you a limited number of moves. Match animals with animals, fruits with fruits, and the other pictures with their own kind.
