Here's the ladder I made, please bare with me, I tried my best.
(updated)
The blurred out lines are fights that will oppose someone who already won and is sure to go on to next round, to someone else who will either be eliminated or go on to next round too. That's because we are not a number of contestant that divides up to well after the 2 first rounds. Did that sound clear? Sorry if it's confusing, it's late and I'm kinda beat.
See you all tomorrow for the tournament!
(BTW If you're not there your opponent wins by default and gets their "winning" prize, you don't get consolation prize if you are not present.)
