We have before us a standard cubical die, like they use for Craps or many well-known board games. It's faces are numbered with the integers 1 though 6, usually represented with dots, in one of these layouts:
The two arrangments are mirror images of each other, and for our purposes are interchangeable. The important thing is that the 1 is opposite the 6, the 2 is opposite the 5, and the 3 is opposite the 4.
One player starts this game by rolling the die. The number is noted and becomes our total thus far. The players then take turns, starting with the other player (not the one who rolled), turning the die one quarter turn, that is, to an adjacent side to the one that was previously "up". The new "up" number is then added to the running total. The players continue taking turns in this fashion until the total is 31 or greater.
The winner is the player to make the total exactly 31, without going over. If the player goes over 31, he or she loses. The player must turn the die each turn, no passing.
Brave volunteers may initiate a game with me by requesting to roll first, which I will do for them (actually I don't have a die handy and will use random.org to pick a number between 1 and 6), or may defer the first roll to me.
Please allow one volunteer to lose before another begins.
For the first member to beat me by making the total 31 or forcing me to go over, I have a DK Forum t-shirt. If you already have one, you're playing just for fun. (And I'll play until somebody without one beats me.)
