You need: 2 players, 2 dice, and several game pieces in two colors.
The first player takes a turn rolling the dice. Multiply the dots by each other, say the product (the answer) out loud. If you are correct, cover that number on the playing board with a game piece. The second person takes their turn. Keep going until one of you wins the game.
If the product you get is covered and there are no open spaces to put your game piece on, you lose that turn.
How to win: The first person to cover four in a row (across, up and down, or diagonally) wins the game.
