Some strategy games give the first player an advantage. If you know how to game the system, you win. Today’s puzzle draws on that theory.
From Your Move: Logic, Math and Word Puzzles for Enthusiasts by David L. Silverman:
“Two players alternately hold up any number of fingers from one to five. The cumulative total is kept and the object is to keep the total prime. The first player who is unable to raise the total to a higher prime is the loser. You draw the first move. How many fingers do you hold?”
Once you’ve figured it out, try it on a friend and let us know how it goes!
