Shut The Box is a classic solitaire dice game where the goal is to remove the numbers 1 through 9 from the gameboard. You remove numbers by rolling the dice, then making combinations from the total on the dice. For example, if you roll a 7, you could remove the numbers 5 and 2. Or if you roll a 9, you could remove 5, 3, and 1. Remove all nine numbers to win!
