To solve a normal Sudoku puzzle, you fill in a 9 x 9 grid of digits, each square containing a digit, 1 - 9 with none of the digits repeated.

In Stars & Stripes Sudoku we still have 1 - 9 and we’ve added three stars. Each row and column now contains twelve spaces instead of nine and the boxes are 3 x 4. Nine of the spaces in each row, box and column will have one of the nine digits; the other three spaces will contain stars.
