A cozy logic puzzle for iOS
Equal cats.
Equal dogs.
Total calm.
Catando is a gentle grid puzzle: place cats and dogs so every row and column balances, no three alike ever sit in a line, and every hint between tiles checks out. Every puzzle is solvable by logic alone — so there's never a reason to guess.
No account. No timer. Free to play.
The only rule you need
Keep it balanced, keep it varied.
No move counters, no combo bonuses to chase — just three quiet checks that every finished Catando grid satisfies.
Equal counts
Every row and every column holds exactly the same number of cats and dogs.
Never three alike
No animal sits three-in-a-row, across or down. Mix it up before you run long.
Follow the hints
= means the pair matches, × means they differ — every hint holds in the finished grid.
That's genuinely it. No timers, no penalties, no made-up combo score — and because every generated puzzle is solvable by pure logic, you'll never have to place a tile on a coin flip. Sir Whiskers only makes this face when you disturb his nap, not when you're stuck.
