[When to hold the event annually]
Feb.~Apr. / Jun.~Aug. / Oct.~Dec.

81Ou tournament is "Ranked Battle Format".
(It's similar to a shogi "Meijin-sen".)

Until you win the 81Ou, 
It will take at least three terms (about one year).
Even if you are strong, you have to start with League-C.
Please continue to participate and enjoy the atmosphere of the ranking battle.

[League-A] -Capacity 15 participants-
Only 15 challengers were selected.
The top league where the fierce players gather is...
Fighting in League-A is truly "the weight of one game".
Whoever overcomes this test becomes the true champion.

・League-A winner is the 81Ou +PRIZE 1500 D-miles.
(Presented by 81dojo)
・Give League-A the semi-title of "12 Generals of Excellent Warrior(十二神将)"
(12 Generals awarded to 14 people other than 81Ou.)
League-A 2nd~10th place and Promotion from League-B 1st~5th place.

[League-B] -Capacity 40 participants-
Residual Pair, Demoted from League-A and Those who won the League-C...
It can be said that it is truly "B-grade of demons".
The important thing is "The weight of one point" and "Ranking difference".
Steadily accumulating winning stars, aiming for all games.
That's what it takes to be promoted to League-A.

[League-C] -No capacity limit-
No matter how fierce you are, the "first step" starts here.
It is important to be able to play as many matches as possible in one match.

-Please be careful-
・Those above "R2500" can not participate.
(*After approval, you can participate only for that period.)
・Proof of your ability (to make a game) is required for those above "R2400".
