After all the food, beer, and booze is laid out, and friends and family start to arrive for your Super Bowl 50 party, complete the get-together with a football tradition unlike any other: a football squares pool. Over the years, "Super Bowl Boxes" or "Super Bowl Squares" has grown into a betting staple for office pools and parties.

The grid may look a bit complicated to the uninitiated, but it’s quite simple to play even if you only watch the NFL or any other football game in passing.

For starters, you have the Denver Broncos on the x-axis of the grid and the Carolina Panthers on the y-axis. It doesn’t matter which team is on either axis if you’re making your own. There are 10 grey boxes for Denver and 10 others Carolina, and each box is assigned a number zero through nine.

The simplest way to assign numbers is writing each one down on a piece of paper, tearing them into individual squares, and then pulling them out of a hat. Once every grey box has a number, pool players can start picking their positions on the board, the white squares.

Your goal is to pick a box that you think best suits your chances of predicting the score at the end of the first, second, and third quarters and lastly the final score of the game. It’s very difficult to predict any score, but the best strategies usual involve 0s, 1s, 3s, 4s, 6s, and 7s.

For example, if the first quarter ends Carolina 7, Denver 3, whichever player has the Panthers 7 box and Denver’s 3 box wins the quarter. In the second quarter, if it’s Carolina 10, Denver 10, then the zero boxes come into play, and so on and so forth.
