Tic-Tac-Toe Percents

What You Do:

1. Decide which player will use Xs and which player will use Os.
2. Take turns selecting boxes and computing answers.
3. If a player solves correctly, they may claim the box by putting either an X or an O in it. For every correct answer, a player also receives 100 points.
4. When a player has attained three boxes in any row, column, or diagonal, they receive an additional 100 points.
5. Play until all of the squares have been claimed. The player with the most points, wins.
