Swirldoku puzzles are just like Sudoku puzzles - only different!
The rules are the same - place each of the numbers 1 through 9 in the open cells so that each row, column, and box of 9 cells contains one of each number. The only difference is that the rows, columns, and boxes are curved. Swirldoku puzzles can also contain more or less than the standard 81 cells in a Sudoku grid.
