You know how #Castings have 20 players with 2 rows of 10?
What if you had to work with the person in your column as a duo? You both have to get as far as you can and either:
(1) The lowest ranked user is the score for the duo, or
(2) Both scores are added up and halfed for the average
You enter the tournament as an individual but play each game with a random partner depending on who ends up below you.
If I was the Games Coordinator, this is a tournament I would try out.
But if is was a challenge people are interested in, we could try and organise it for January. I don't have any prizes to offer though. 馃槕
