Easy to learn
Look, compare, tap. No tutorials, straight into the fun.
Two pictures.
Spot every change.
Two pictures of the same cosy cat room sit side by side. Tap every little thing that changed before the timer runs out.

Free in the browser: Classic mode, the first 10 levels, three cats and one cat to adopt.
Ten worlds, from a cosy cottage to a moon base and the Cat Palace. Each room brings new tricks: changes that move, colours that barely shift, a kitten who sits on the picture, rooms lit only by a torch, and a magpie boss at the end of every world.
Levels 1 to 10 are free right here in your browser. The app unlocks all 100.
Buddy, Mochi and Zoe are drawn from three real cats. Then adopt up to three of your own: pick a coat, reroll the markings and give your cat a name. The first adoption is free; the full game opens two more.
Look, compare, tap. No tutorials, straight into the fun.
Subtle colours, moving tails, slow changes and night rooms keep your eyes busy.
An endless run of rooms on one timer that every find tops up.
No account, no internet needed once it's installed.






Play the first 10 levels free right here. The app for phones and tablets unlocks all 100 rooms in 10 worlds, 2 more Adopt-a-cat slots and no more ads with one small purchase. No subscriptions.
