I found two minigames in the first area of The-Witcher-2, an Arm-Wrestler, and someone who wants to play "Dice Poker". While the former is simply explained in the in-game help, there was no information on how to play Dice Poker.
What do the symbols on the dice mean?
What do the (unlabeled!) circles under the bet screen do? (I believe the left is forfeit, and the right is call, but I'm not positive)
