How to play

Find every cat its own space

  1. Place exactly one cat in each row and each column.
  2. Each colored region needs exactly one cat. Letters also identify the regions.
  3. Cats cannot touch, including at the corners. They can share a longer diagonal.
  4. Tap an empty square to place a cat, tap again to mark X, and again to clear it.

A good place to startLook at the smallest region first. Imagine a cat in each of its squares and see which choice leaves room for the other cats.

Striped squares break a rule. Check outlines marks that disagree with the solution, and Hint reveals or corrects one square. Use as much help as you like.

How this cat sudoku puzzle works

Often called cat sudoku, this is a Queens-style placement puzzle rather than a number puzzle. The colored regions, rows and columns work together to narrow down each cat's home. Start with the small regions, mark squares that cannot hold a cat, and return to the board after every new placement. Each of the six 5 by 5 boards has one solution.

A few things to know

Is Cat Queens the same as regular Sudoku?

Cat Queens uses one cat per row, column and colored region, plus a rule that cats cannot touch. Regular Sudoku uses sets of digits and boxes. If you prefer that format, try Mini Cat Sudoku.

Can two cats share a diagonal?

Yes, if they are not next to each other. Only touching corners are forbidden; this is not the chess rule that blocks an entire diagonal.

Can I play without signing in?

Yes. All six games are free to play as a guest in your browser. You do not need an account, a download or a virtual pet.

Will my progress be saved?

Your puzzle boards, management games and arcade best scores are saved separately in this browser when device storage is available. They do not sync between devices, and clearing site data removes them. You can still play if storage is unavailable.
