Sten, Sax, Påse: Superdueller

This is card-game variant of the classic game "Rock, Paper, Scissors", in which players challenge each other to fast-paced and mixed duels. In this game you get 50 varied duels that utilize speed, calculations and/or risk taking. How about playing so that you announce what you're going to choose, and if you really go through with it and win, you get 2 points? Or how about whoever wins with the same symbol two rounds in a row, win the duel? And how does the 'well' symbol actually work?
