Drinking game with 2x d6.
Roll dice. Don't show. Read outcome to the next player. 6 and 4 is always 64, never 46. 1 and 1 is 100. The top is 1 and 2, "Macháček."
You have to roll more or same than the player before. The one after you has to roll same or more.
So you roll and declare to the next player. He either accepts, or says you're lying forcing you to reveal. Looser drinks. With beer it's an ok and fun game. When slivovice gets involved, it's murderous.
