Sink or Swim

"If we're going down, we're going down together! IN this game of doublethink, everyone contributes dice to the center, then competes for them. Use the same tactics as another player, however, you will sink!"

This simultaneous play has you rolling two dice and putting them into a pool in the center. Then you secretly set a die to what you think you want to pull from the center with each matching die equating to a point. The problem is you lose points for each matching die when another person also sets their die to that value. Set it to a value that isn't in the pool and neither gain or lose points. After 10 rounds, see who has the most points!
