A traditional betting pool takes place during the Super Bowl, where entrants make random picks for the score of the game. These entries are known as “squares” where players either pick or are assigned a cell in a 10 by 10 grid. Then after the grid is filled, the rows and columns are assigned a digit (0-9) which corresponds to the final number in the score of each team. The player with the correct combination wins, and prizes may be paid out for having the correct score at the end of the game, at the halftime and for each quarter. (資料來源)
