Hello, to be more clear, we set it up squares as HOME TEAM vs AWAY TEAM but the grading and the winning squares will be automatically winning team/higher scoring team-losing team/lower scoring team. We have been doing Nitro Squares like this from the start.

To be more specific on declaration of winners of Nitro Squares as part of the rules:

• The winning square will be the last digits of the final scores of the two teams involved in a particular game.
  The winning team’s last digit in their final score will be the first number and the losing team’s last digit in their final score will be the second number in the winning square.
  Example: The final score in a Memphis Grizzlies vs. Los Angeles Lakers game is Grizzlies 105, Lakers 91. The winning combination for this particular game/example would be 5-1, which means entries under 5-1 will be declared the winners.
