Catdoku

Overview of Catdoku

Catdoku is a cute and cozy cat-themed logic puzzle game where you determine the only valid position for each cat on a colorful grid. Instead of filling cells with numbers like traditional Sudoku, you use deduction to place exactly one cat in every row, column, and colored region. There is one more important rule: cats like their personal space, so no two cats can touch, even diagonally. Mark impossible cells with Xs and gradually narrow down the remaining possibilities until every cat has a home. As the boards become more complex, solving them requires careful observation, elimination, and planning rather than random guesses.

Key Features of Catdoku

• Cat Logic Puzzles: Find the correct position for every cat through deduction.
• Multiple Placement Rules: Each row, column, and colored region needs exactly one cat.
• No-Touch Rule: Cats cannot sit next to one another, including diagonally.
• X-Marking System: Rule out impossible cells to narrow down each solution.
• Progressive Difficulty: Solve increasingly complex grids as you advance.
• Hints: Get help when you become stuck on a difficult puzzle.

Core Gameplay Mechanic

Catdoku is about eliminating impossible positions until only the correct cells remain. Every cat you confirm changes the possibilities across its row, column, colored region, and neighboring spaces.

• Find the Right Place for Each Cat: Study the entire grid before placing a cat. Each row, column, and colored region can contain only one, so a position that looks possible at first may become invalid when you consider all three restrictions together.
• Mark Impossible Cells: Use X marks to eliminate cells where cats cannot be placed. Once a cat is confirmed, rule out the rest of its row and column as well as every neighboring cell, including diagonal spaces. These eliminations can reveal the next forced placement.
• Solve Without Guessing: Look for rows or regions with very few possibilities and work outward from certain placements. One correct deduction can trigger several others, gradually revealing the complete solution. Random cat placements can cost you a fish, so careful reasoning is the safer strategy.
