From the Patch Products Press Release:
This game is played on nine Tic-Tac-Toe grids. On each turn, players roll two dice, add up the numbers and mark a corresponding number with their color. If a player marks his or her color on three numbers in a row—either vertically, diagonally or horizontally—they score!
The game was created by David Jisa, a Wisconsin teacher who uses games in his classroom to help motivate students. Roll-It Tic-Tac-Toe lets students practice their addition skills and develop problem-solving strategies.
Roll-It Tic-Tac-Toe comes in two versions—one with colored chips and 8 game boards and another with colored markers and game sheets. The game is for 2 to 6 players ages 7 and up.
