About the game
CatDoku is a cosy logic puzzle in which you place cats on a coloured board. Each row and column holds exactly one cat, each colour zone holds exactly one cat, and no two cats may touch, including diagonally.
The rules are simple, but the levels become trickier as you move through more than 100 of them. You tap an empty cell to place a cat and tap again to remove it. It suits fans of sudoku-style puzzles who like careful deduction.
