The rules are very simple. The numbers 1 through 9 are "open". Two dice are rolled and numbers are shut that sum up to the number rolled. A player keeps rolling until no numbers can be shut, at which point that player's score is the sum of the numbers still open. The goal is to score as low as possible.
Luck is a big factor here, but is there a strategy to this game? Does the strategy change based on the numbers still open?
