This math game is deceptively simple. You roll a number cube (we used ones from 0-9 but a regular one would work fine) four times. Then you choose three of those four numbers to make a three-digit number. You are creating several three digit numbers and writing them in order from smallest to largest. If you are not careful about where you place a number in your list, you will have trouble creating a new one to fit in the spaces that are left. It requires some planning and thinking!
