# Stars & Stripes Sudoku

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.

Although the puzzle is shaded for appearance, the shading doesn't affect how the puzzle is solved.

4 | 1 | * | 5 | 8 | 2 | * | 9 | * | 3 | 6 | 7 |

6 | 3 | 8 | * | ||||||||

2 | 7 | 9 | * | ||||||||

* | |||||||||||

5 | |||||||||||

3 | |||||||||||

7 | |||||||||||

8 | |||||||||||

9 | |||||||||||

* | |||||||||||

1 | |||||||||||

In this example, you can see that the filled in row, column and the box each have 1 - 9 and three stars.

Remember that unlike digits, stars are all the “same”. Having one star in a row, column or box doesn’t prevent it from having others. In fact, there are always three of them.
