Catdoku is a charming cat-themed puzzle game where you place exactly one cat in each row, column, and color zone. Cats cannot be placed next to each other—even diagonally or by merely touching corners.
Catdoku takes the familiar Sudoku framework but replaces the numbers with colorful cats sitting in the grid squares. The game looks calm, but its rules are strict. Every row, column, and color region needs exactly one cat, and felines can't touch each other, even at the corners.
Look over the board and work out which squares can't hold a cat. A square is ruled out if its row, column, or color region already has a cat, or if it sits next to one.
Repeat the process of scanning rows, columns, and color zones until every cat has found its spot. Tap a marked square again to clear it and try a different move.
2–3 empty cells — Solve these first. Fewer open cells mean the correct placement gives itself away sooner.
Many empty cells — Hold off for now. Wait until nearby rows and columns narrow things down first.
Mark the impossible first — Cross out cells you're sure are wrong before guessing where a cat goes.
Check all 8 neighbors — Mark every surrounding cell, including the four diagonals, right after placing a cat.
The general rule is to start with the areas that offer the fewest options. Solutions reveal themselves more quickly in crowded zones, whereas guessing in open areas when the board is still mostly empty often leads to having to undo your moves and start over. Catdoku starts with small, approachable boards but soon advances to larger grids featuring winding colored zones and ever-changing daily challenges—enough to keep both newcomers and seasoned players hooked.
After giving your brain a workout with the intricacies of Catdoku, why not try Tiny Garden War? Plants replace cats, and zombies take the place of the empty grid spaces requiring calculation; you still get to put that sharp mind to work, only this time you’re building defenses instead of placing cats into slots.
