What is 81Ou League

• 81Ou League is the primary championships of 81SquareUniverse.com. The players will compete for the supreme title "81Ou".
• "81-Ou" (八一王 in Japanese kanji) means "the King of 81-Square Universe".
• Just as in professional "Ranking League", the players are classified into several leagues according to their strengh. (such as A-Class, B-Class, C-Class, etc.)
• The winner of A-Class becomes the challenger to the title holder, 81Ou.

Rules

• The league is run by Round-Robin System.
• Each game is played at 81Dojo, with 15 - 60, rated.
  
• Player gets:
• 3 points for win / win by default
  
• 2 points for draw  (or play a rematch)
  
• 1 point for loss
• 0 point for loss by default
• Player must try to finish each game around the recommended date specified for each game. (2 games per month in average)
• If you know that you won't be available to play in some period of the term, you can in advance discuss with your opponent and the administrator about changing the schedule for the games of that period.
  
• If the two players seem to be unable to arrange the schedule despite that both players are willing to, (due to time difference, or both players' being too busy, etc.),

1. they may discuss delaying the schedule with the administrator.
   
2. they may agree on "draw by default", receiving 1 point each.

• Both of the players receive 0 point (loss by default) for a game that hasn't been resolved in the recommended period with any of above.
• If a player has made 3 losses-by-default without any communication, he/she is disqualified from the league in that term, and cannot register in the next term.
• Additionally, for newly registered players, 2 consecutive losses-by-default without communication on the very first 2 games deserves a disqualification.
  
• If two or more players have the same points, the player with less number of loss/draw-by-defaults will be ranked higher.
• If two or more players have the same points, and the same number of loss/draw-by-defaults, the rank is decided according to the result of their direct game that has been played. However, if that happens for 1st rank in A-Class, playoff (challenger deciding match) will be played.
• If the rank couldn't be decided with above principles, the player who is higher in the match table is ranked higher.
  
• The title match is played as a 5-game match (in other words, 3-win match). The loser of the title match is qualified for A-Class (ranked in 1st) in the next term.
• The league classification for the term is usually determined according to the player's results in the privious term. A new member will be enrolled in the lowest class. One's qualification for the league remains valid for 1-term absense.
• If you run into another league member at 81Dojo by coincidence, (whom you haven't made appointment with yet), you may agree to start the league game immediately there without an appointment. (But when it's a lot earlier than the recommended period, maybe you should wait until the time comes.)
