What is Meowdoku?
Meowdoku — also written meow doku, and often called cat sudoku or meow sudoku — is a free logic puzzle where you place cats on a colored grid. It keeps the careful deduction of Sudoku but swaps the numbers for cats, so it stays friendly even if plain Sudoku feels intimidating.
You never write a single number. Every board is solvable by pure logic with one correct answer — no guessing, no math, just a few calm minutes of deduction. If you have played LinkedIn's Queens puzzle, the rules will feel immediately familiar.
