Catdoku

Catdoku swaps numbers for colored regions and a crowd of cats. You place one cat per row, column and region, and no two may touch. Logic decides every single board.

How to Play

• Put exactly one cat in each row, each column and each colored region.
• Cats may not touch, not even at the corners. The game calls this the Aloof Rule.
• Click a tile once to mark an X where a cat cannot go.
• Double click a tile to place a cat.
• Press a filled tile again to erase it.

Standout Features

• No numbers anywhere, so the puzzles read the same in any language.
• Small starter grids that teach the rules, then bigger boards with twisting regions.
• Daily challenges with new layouts and a chance to beat your own solving time.
• Bright colors and cat artwork that keep a tough puzzle pleasant to look at.
• Strict rules that punish careless placements.

Tips for Solving Faster

• Start small. A region with only two open cells is your best entry point. Test both cells and see which one leaves the board intact.
• Cross out as you go. Each cat removes its row, column, region and the eight cells around it. Mark them immediately, or you will drop a cat somewhere illegal by accident.
• Look for lines. If a region sits entirely inside one row, that row belongs to it. Every cell of another color in that row can take an X.
• Compare regions with rows. When three regions are squeezed into three rows, those rows are spoken for. Strike everything else inside them.
• Find shared neighbors. A cell that touches every remaining option of a region cannot hold a cat, because placing one there would erase that region completely.
• Rescan after every move. One new cat often turns a vague spot into a forced answer.
• Stuck? Pretend. Place a cat on a doubtful cell and follow the results. If the board breaks, that cell gets an X.

Who Will Enjoy Catdoku

• Catdoku fits fans of Sudoku, Queens and Minesweeper who like clean deduction.
• Commuters get short sessions that fit into a coffee break.
• Anyone who prefers reasoning over arithmetic will feel at home.

Worth Your Time?

The rules fit in one breath, yet a hard board can hold you for ten minutes. That gap between simple rules and real depth is what makes this puzzle stick. You never need luck, because every board has a single answer that logic can reach. When you get stuck, the way out is usually a cell you skipped, a region you misjudged or a line you forgot to check. Finding it feels earned.

The pace is easy to manage. A quick grid fits into a short break, and the larger boards reward a slower evening. Daily challenges give you a reason to return, and beating your own solving time is a small goal that keeps the habit going. Start with the smallest region and see how far a single cat takes you.
