Standard Sudoku Rules apply to the final numerical layout.

Digits on the football, the solid grey lines, are limited to the four possible point values in football: 1, 2, 3, or 6. Digits on those lines do not touch themselves diagonally on any other part of the lines.

The two end zones are designated by the dashed lines and the two little killer arrows; the final scores of the two teams, 21 to 22, are the sums of the digits along the indicated diagonals.

The coaches' playbooks have circles and arrows indicating important plays for the game, and the digits along the arrows sum to the digits in the circles, which may repeat if allowed by Sudoku.

And along the sidelines, spectators watch while eating Sandwiches. The Sandwich numbers indicate the sum of the digits between the 1 and the 9 in the indicated rows or columns.
