Tourneys uses the Knockout Mode in playing.
Here's how it works
1) At the start, there are two players playing and i think you already know that. After they have finished playing, whoever wins will be putted on to the last queue and the one who have lost will put to spectator mode.
2) After the 1st match, the person in queue #1 and queue #2 will be the one who will fight next. And the same thing will happen after their match.
3) for short, it means every two players will be matched up and the one who will lose will be put to spectator mode until only two players are left. The one who won the last match will obviously be the champion and gets the TC.
Actually, tourney uses wushupro. Before it was wushu but now they changed it to wushupro to have more challenge in the game.
Wiki is down for sometime. I think they are fixing it.
