ABSTRACT

Since the Race to 100 Game was based on addition of numbers, how about a game that uses subtraction? This game is a game of chance. It can be played on your own or with friends.

You will need a die, that is, one of a pair of dice, or, if you don’t have a die, make yourself a spinner with the numbers from 1 to 6 on it. The game of Roll Back works like this. Starting with the number 100, subtract numbers determined by rolls of the die. The objective is to roll back as close as you can to 0 with no negative numbers allowed.
