Cf. qeylIS mInDu' "Eyes of Kahless" - a guessing game with dice where the winner receives a punch - in KCD: "You roll two dice (I think they have more than six sides), and the other person snatches one in each hand before you can see how they came up. Then you slap the hand that you think has the die with the higher number on top, and if you're right, you win. There can be some additions for extra flavor, such as spitting into the hand with which you're rolling, or taking a Daqtagh and striking it down on the table between the two hands." (qoror)  "And IIRC one of them gets punched in the face...of course." (DloraH)
