Cat puzzle solver (works for Meowdoku boards)
Copy the color areas from the puzzle you are stuck on, then reveal one cat at a time or the whole answer.
Cat Sudoku is an independent site, not affiliated with Meowdoku or its developer. This free tool works for any puzzle with these rules.
1. Pick a color, then tap or drag over the squares that have that color in your puzzle.
2. When every square is colored, choose how much help you want.
How to use the cat puzzle solver
- Pick the board size. Count the squares across your puzzle. A board with 8 squares in a row is 8 × 8.
- Copy the colors. Choose a color in the palette and tap or drag over every square of the matching area in your puzzle. The colors here don't need to match your game's colors; they only need to group the same squares together. Thick lines appear where one area meets another, so you can compare the shapes at a glance.
- Get help. Press Show one cat to reveal the answer one row at a time, so you can keep solving the rest yourself. Press Show all cats to see the full answer.
The solver checks every possible arrangement, so the answer always follows the rules: one cat in each row, column and color area, and no two cats touching, even diagonally. It runs in your browser; the colors you enter are not sent anywhere.
If the solver says something looks wrong
- "Some squares have no color yet": every square needs a color before the solver can work.
- "A board needs exactly … colors": an 8 × 8 board always has 8 color areas. Check whether two areas got the same color, or one area got two colors.
- "No arrangement of cats fits": a square is almost certainly copied into the wrong area. Compare the thick lines with your puzzle row by row.
- "More than one answer fits": a well-made puzzle has a single answer, so one square is probably in the wrong area. The answer shown still follows all the rules for the colors you entered.
Solve it yourself next time
A solver gets you unstuck, but the fun is in spotting the moves. The Meowdoku rules and strategy guide walks through the techniques that crack most boards: starting with the smallest area, crossing out around every cat, the two-by-two block trick, and counting areas against rows. You can practice all of them on the free Cat Sudoku puzzles here, with 320 levels and a daily cat.
The solver works for any puzzle that uses these rules, including Star Battle style "one star" puzzles and LinkedIn Queens boards.
