Super Bowl squares are a yearly tradition for the NFL's championship game. DraftKings and FanDuel have their own versions that add skill to the mix.

The squares game depends on the final digit in each team’s score, and can be played in several formats. It’s a random game, but it resets at the end of every quarter. So, even a blowout game on the gridiron can hold some suspense on paper. Plus, it can be a lot cheaper than placing a bet with a Las Vegas sportsbook.
