The numbers 0-9 were randomly assigned to the columns and rows.
The Super Bowl teams are listed on each respective axis (top and left). The top numbers represent the last digit of the Eagle's score and the left numbers represent the last digit of the Chief's score.
Whoever has the correct digits at the end of the 1st quarter, halftime, 3rd quarter, and final* score wins a QA Gift certificate. For example, if the Chiefs are beating the Eagles 10-7, the winning square would be where the No. 0 on the Chiefs axis meets the No. 7 on the Eagles axis.
*In the event of overtime, the final score will determine the final winner, not the score at the end of the fourth quarter.
