Muggins!

Add, subtract, multiply, and/or divide three (3) numbers shown on the dice to produce an answer. Try to make an answer that helps build and run for you (bonus points) or blocks your opponent's run. Throw in a bluff or challenge your opponent's answer as you try to outwit and outmaneuver each other in this analytical aerobic workout for the mind!
