About This Game

Small cats. Big chonks. A very full box.

Mochi Cats is a cozy physics puzzle about finding room for an increasingly chonky collection of cats. Rotate and drop pairs into the box, bring matching cats together, and watch them merge into bigger, rounder companions. Keep your growing pile below the line to keep the run going.

Grumpy cats need their space

Not every cat is here to make friends. Grumpy Cats don't want to meet each other. Keep them apart for 10 drops to make them happy.

A little snack. A little space.

Every merge brings your next treat closer! When a treat is ready, give it to a cat to send them out of the box and free up room. Even grumpy cats can be tempted.

Make the pile your own

Unlock themed cat sets and room backgrounds through the Chonk Pass (completely free!), a permanent reward track earned by playing. Every merge brings you closer to a new look. Mix your favorite cats with your favorite room.

Just one more box

How high can you score before the box fills up? Chase a higher score and see how you stack up against friends and players around the world.
