How to use this Cat Sudoku solver
Players may call these puzzles cat sudoku or meow sudoku. This tool handles Cat placement, not traditional 1–9 number Sudoku: one Cat per row, column and colored region, with no touching even diagonally.
- Choose a 6–12 grid, paint the regions, or upload a screenshot and align its grid, group colors and correct the regions. Screenshot input still needs your review.
- Add fixed clues and keep your current attempts under My marks. Check the board and correct any conflicts.
- Ask for a verifiable hint or find the full solution. If a complete answer requires search, the tool does not describe that search as a logical deduction.
