CatDoku

About CatDoku

CatDoku is a cozy logic puzzle from ONLYDRK Studio where fluffy cats take the place of numbers. Three rules govern every board: one cat per row and column, one cat per colored zone, and no two cats in neighboring cells — diagonally included. Simple to grasp, but the levels grow progressively trickier as you advance.

How to Play CatDoku

The goal is to fill the board so all three rules hold simultaneously. Tap an empty cell to place a cat, tap it again to remove it, and keep arranging until no rule is broken.

Tips & Tricks

• Start with rows, columns, and colored zones that have the fewest empty cells remaining.
• After placing a cat, mentally eliminate its neighboring cells along with its entire row, column, and color zone.
• When stuck, use the hint to reveal a correct position.

Work through 100+ levels to reach CatDoku master status.

Controls

• Tap empty cell: Place a cat
• Tap again: Remove the cat
