If you are in The Duel and if its in fast mode then there should be a duel where the duelers have 2 minutes to click "start" within the same 2 minutes of eachother and its a LIVE duel challenge. One challenge could be like a Shuffle board and the person to get their puck closest in the middle of the circle wins or something.. that'd be really cool and more strategical than reptitive games like guitar,numbers & you can feel confident taking in anyone because its a FAIR game.
