There are four prizes. At the end of each quarter (or first, second, and third quarters and the end of the game, in case of overtime), the winner will be determined by intersecting the column and row whose numbers match the last digit of each team's score.
You may buy up to 10 squares. All funds are due within 5 days of picking squares. Money not received within 5 days of picking squares will cause the squares to be released back into the pool.
