The players (open circles) will run their assigned routes and blocking schemes (arrows). To run the routes correctly, the digits along the arrows must sum to the number in the circle. The endzone (row 1) will be painted in alternating colors (of your choosing: the grey circles hold odd numbers; the grey squares hold even numbers.) There was a penalty flag thrown on the previous play (the X). It was a 10 yard penalty (meaning the 2 digits surrounding the X must sum to 10). Normal sudoku rules apply.
