We have two kinds of Tournaments:

 Quick (8) and Classic (16) tournaments

Special (league-like) tournaments

 The first type of tournaments are quick and classic tournaments for 8 and 16 players. They are always available and will start when enough people have entered. The league tournaments will start at a predefined set time and date. If you’ve started a quick tournament, do not leave the tournament lobby when you are waiting for a game. The Special league-like tournaments are available for unlimited number of players, so everyone can join. Again, do not leave the tournament room if you are waiting for a game.
