I have an idea for one, not sure if it would take off.
Confidence Picking.
Essentially you pick any 3 games of the round, and rank how confident you are on them.
ie
Red Vs Blue - 3
Green Vs Purple - 2
Yellow Vs Orange - 1
Essentially I am wagering 3 points on Red to beat Blue, 2 points for Purple to beat Green, and one point for Yellow to beat Orange. If those results all come through, I end the round with 6 points.
The kicker is, for any incorrect result, you get that amount of points deducted. Potentially you could get - 6 points for the week if you pick wrong.
With a potential 12 point swing on any given game week, if we get numbers to join, then it could keep interest for the season
EACH PLAYER ALSO GETS A MAGIC ROUND TOKEN - This can be used during ANY round. When played, that players score gets double, and an incorrect selection does NOT minus any points. Potentially winning up to 12 points, without danger of losing any points.
