Maybe I just need to read more carefully but I had some questions.
Only one match for each player can go at once right? So if 2 challenges 1 and 3 challenges 2, whoever challenges first will get their match while the other person waits for a challenge?
If that is the case, is there a time limit after a failed challenge before you can challenge again? Or a time limit on challenging for the spot you just lost?
If there is only one match allowed per player at once, how many matches does player 10 need to play before he can challenge player 9? After initially losing to player 9 the first time?
