Sudoku is a wildly popular Japanese puzzle, traditionally played with numbers. We've replaced figures with nine Halloween cats, but otherwise the rules are the same:

- An individual cat can appear only once in any 3 X 3 box.
- An individual cat can appear only once in any row of the entire grid.
- An individual cat can appear only once in any column of the entire grid.

There's no right or wrong place to start--click on the board to the right and try to outwit the Halloween cats!
