Rock Paper Scissors
Two people are playing rock-paper-scissors and paper folding, and you have to announce the winner in each round. The rules are the same as any rock-paper-scissors game, and all you have to do is choose which side wins, or in case of a tie, call it a draw. You also have a time limit to announce the result, and if you don't do it within that time or miscalculate the result, you lose one turn directly. You have 5 lives, so you can make 5 mistakes.
