The 2020 Super Bowl between the San Francisco 49ers and Kansas City Chiefs takes place in just a few hours today, which means time is running out to participate in Super Bowl squares. Popular in office settings and at Super Bowl-watching parties, squares is a simple way to inject even more excitement into one of the world's most popular sporting events. With a little skill, the game can be profitable too.

Super Bowl squares is simple to set up. First, the organizer draws a grid that's 10 columns by 10 rows, resulting in 100 squares. One team, either the Niners or Chiefs, will be assigned the columns, while the other team will be assigned the rows. Finally, each column and row will be numbered zero to nine.

Players then select the square or squares they want. The winner will be the person who owns the box that corresponds to the last digit of each team's score. For example, if the final score in the Super Bowl were Kansas City 24, San Francisco 9, the person who owns the box with Kansas City four and San Francisco nine wins.

Some versions of Super Bowl squares randomly assigns the numbers until after each of the squares is spoken for, while others auction off each square. Some Super Bowl squares pay out only the final score of the game, while others do so after each quarter or every scoring play.
