It is basically rock paper scissors. Queen beats King, King beats Joker, Joker beats Queen. To start a new round click the green flag. Controls P1- Queen=a Joker=s King= d P2- Queen=left arrow Joker=down arrow King=right arrow The game will wait for both of you to choose.
Sometimes it glitches and displays the win screen randomly. If that happens just restart by clicking the green flag.
