This will be disqualified upon notice.

(Please check the BMS terms below to learn more about what constitutes as an incomplete entry)

Also, not exclusive to this event, many people can not register due to registration errors caused by missing required items when trying to register before the deadline.
Registering takes time, so please register within a decent margin before the deadline.

In order to avoid server overload, the public release of songs is done during the registration period.
However, this date is not yet announced.

If these conditions are met during the registration period, the song will be made public at that time:
・Sponsored by BOFU by getting AA or higher (AA- does not count) on the song "The Legend of MAX" [ESP] on DDR A.

※ These conditions are subject to change without notice.

Prohibitions For All Participants

Ace Song System

The Ace Song System lets you have a single ace song when registering songs.

Team Scoring

We will calculate the team total score differently per department,
based on the impressions for each song per team.

Team Median Score Department

In this department, we take all the scores for a team and put them in ascending order and find the center number, the median.
Winning or losing depends on the median score of the impressions. Please note that this is a different aggregation method than the average score.
In addition, the median score department will only count teams that put out the number of entries declared before the registration period.
Also, the score bonus from the ace song system is not applied.

Team Total Score Department

This department calculates the total score from the impressions for every entry in a team.
Unlike the median score department, it will not be lowered by impressions with low scores.
In addition, for Ace songs there is an additional bonus where the songs' total score is multiplied by 1.25.

Single Scoring

For the sake of reference, we will also publish a division that ranks all the individual entries without considering the teams.
These departments only exist as reference points and do not affect the team score departments whatsoever.

Single Median Department (For Reference)

The aggregation is the same as the team median department, where all impressions scores are sorted to find the value in the middle, the median.
We will rank the median value for each song. Ace song bonus is not applied.

Single Total Score Department (For Reference)

In this department we calculate the total score based on all the impressions on a single entry and determine the rank this way..
Unlike the team total score department, the ace song bonus is not applied here.

Team Aggregation Method

Song Amount Total Score Department Median Score Department
2 ((Total score of each song × 1.5) × 2 songs) + Ace song bonus points All the individual scores for each song (2 songs) are sorted in ascending order and the number in the center, the median, is located.
3 Total score of each song (3 songs) + Ace song bonus points All the individual scores for each song (3 songs) are sorted in ascending order and the number in the center, the median, is located.
4 ((Total score of each song ÷ 1.33) × 4 songs) + Ace song bonus points All the individual scores for each song (4 songs) are sorted in ascending order and the number in the center, the median, is located.
