Rules applying to all participants.

※ Impression period may be subject to change based on number of registered teams.

Works that do not meet the registration period deadline will be disqualified at that point. Please be aware of this in advance.
Teams that do not meet the required number of submissions as explained later will be excluded from the scoreboard in certain categories.
In addition, to address the issue of extreme server load at the registration deadline, we have implemented an overtime registration system
that allows for a few minutes of registration processing after the registration period ends. Works registered during the overtime period will not be disqualified.

We are not going to have one this year.

Registering only the information of the work without any playable BMS downloads available,
or registering works that are incomplete at the time of registration would be considered as an Incomplete Registration.
(Please refer to later section for what would be considered incomplete)

Also, there often are participants who attempt to register right before the registration period ends and fail to do so because they did not fill all required information. Make sure to have plenty of time to register, since registering song data takes time.

The administrators reserve the right to, without notice, issue a violation warning or delete any impressions / works that fall into the following categories.
Furthermore, depending on the nature of the violations, it is possible that team members of the violator would be disqualified as well.

• Posts/Works that intend to slander, defame, or abuse a specific individual.
• Posts/Works that intend to threaten, extort, or coerce a specific individual.
• Impersonating someone by using their handle, or malicious imitation.
• Posting impressions for the purpose of receiving rewards, regardless of the currency or amount.
• Posts/Works that are intended as hate speech.
• Posts/Works that are intended as propaganda.
• Works or impressions registered or posted using fraudulent methods
• Using the system within the venue, such as comment sections, to send absurd messages or perform disruptive actions. (no trolling)
• Any other actions that the administration deems inappropriate.

Any of these found on the venue will be addressed upon reports from other participants or as soon as they are discovered by the event staff.
However, if the reported content is clearly not applicable or deemed not problematic by the administration, no action will be taken.

Additionally, if the following actions occur either within or outside the venue (such as on the web, social media, forums, open servers of chat tools, etc.)
and are deemed problematic by the administration, the impressions or works of the participants or parties involved may be disqualified, invalidated, or deleted:

• Threatening, blackmailing, or coercing event participants or the administration and its associates.
• Bribing evaluators or work creators to influence evaluations, regardless of the currency or amount.
• Concealing known misconduct by team members within the team.
• Sharing or leaking passwords used at the event venue with unrelated persons without a special reason.
• Repeatedly making aggressive remarks or slandering the administration, its associates, or event participants.
• Any other actions deemed inappropriate by the administration, or those that may hinder future event progress.

The above actions will be investigated by the administration upon discovery of the issue. If after the investigation, it is determined that there is no problem, no action will be taken.

In the case that a participant repeatedly engages in the actions listed below,
we will ban that individual from participating in all future events hosted by us.
Additionally, depending on the nature of the violations, we may immediately ban the participant even if offenses are not repetitive.

If it is determined that the banned person is participating under any name,
we reserve the right to disqualify the team in which that person is participating, and delete impressions without notice.

• Participants who created BMS that were disqualified by special measures taken by the organizers
  (Works that fall under voluntary withdrawal or preliminary registration are excluded）
• Participants who repeatedly violated items 3 to 7 of the impression regulations (detailed below)
• Other participants deemed problematic by the organizers, such as those who made threaten staff or other participants

These rules have been in effect since 2020, and have been applied in all events hosted by us.
We may expand the scope of application of above rules to include activities outside the venue (Web, SNS, email, inquiry forms, forums, chat tools, etc.) and judge based on all actions 2019 onwards.

We will not be involved in any trouble caused by individual participants or between participants,
And will not be responsible for any damages or losses caused by the trouble.
Regarding incidents of online backlash on external social media or forums caused by personal remarks or actions of yourself or participants from your own team, please take responsibility and resolve the issues on your own.
Even if we receive opinions, requests, or reports regarding external backlash incidents, the organizers will firmly refuse to engage in any form of assistance or intervention.

Without permission, it is forbidden to share the content of emails or DMs anywhere the content can be viewed by an unspecified large number of people.
Recently, there have been many instances where the content of emails or direct messages has been shared via screenshots without our permission.
Such actions not only constitute a violation of privacy but also affect the trustworthiness of the poster.

Please consult with us in advance if you wish to disclose the content of emails or direct messages. We may grant permission depending on the reason for disclosure.
If messages are shared without permission in the future, we will treat it as an "Any other actions deemed inappropriate by the administration, or those that may hinder future event progress."
listed under the actions prohibited to all participants. We will delete or disqualify the works or evaluations of the team involved in the violation.

This event may be canceled due to unavoidable circumstances, regardless of the event's duration.
If the cancellation is confirmed and all submissions and evaluations up to that point are valid, we will announce the results based on the current tally at a later date.

You must apply for participation in advance in this event on the dedicated registration page.
Please note that teams that have not applied for participation in advance will not be allowed to participate.
The registration page has been announced on the top page. Please be sure to check the team registration period if you are considering registering.

In this event, the person who is in charge of the process of slicing sounds, arranging sounds into a BMS file, and creating at least one chart would be considered as the BMS creator, and all persons who are not BMS creators (e.g., composers, arrangers, movie creators, chart creators, vocalists) are considered support members.
All persons involved in the team should be entered as members during team registration. The minimum number of team members is determined by the number of submitted works, with 3 members required for 3 works and 4 members required for 4 works.
BGA (BGI) creators, vocalists, performance assistants, chart creators, and anyone involved in BMS creation are considered as members.
Members can be freely changed after registration; however, if the listed members significantly differ from the actual members, the team may be disqualified.

An individual is only allowed to be a leader of a single team.(※2)
The team will be disqualified if it is found that any of the listed team members have been added to the team without their consent, or that the team has faked the number of team members in order to reach the minimum number of team members.

BMS creators and chart creators must be credited under either the ARTIST or SUBARTIST header in the BMS data.
Works that do not comply with this will be considered that the involved BMS or chart creator is not responsible for the work.

※1……Inflating the number of members using aliases will not be allowed.
※2……Team leaders cannot serve as leaders of multiple teams. However, they can hold other roles in different teams as long as they are not the team leader.

To participate in this event, you must register your team in advance. An email address would be required to register.
Teams that failed to register within the Team Registration period cannot participate.
Teams that fall under the following conditions are not eligible for registration and participation:

If a team is found to fall under these categories after registration, they will be disqualified or have their registration revoked.
Participants who have been disqualified or had their registration revoked can reapply only once during the team registration period. However, if they are disqualified or have their registration revoked a second time, they will be banned from participating in this year's event.

When registering a team, you must declare the number of works your team will submit. The number of works that can be declared is 3 to 4 per team.
The number of works can be changed from the time of registration until one week before the event. If the declared number of works is not submitted, the missing works will be treated as 0 points in the total team score category, and they will not be counted in the median team score category.
One of the declared works must be selected as the "FINAL STRIKER", which will be handled under special rules.

In recent years, there have been issues with our email server used for the BOF related mails. As a result, some email services have experienced delivery failures or delays of mails from us.
As of 2024, it has been confirmed that email services such as Naver, Outlook (formerly Hotmail), and Tencent QQ cannot receive or are delayed in receiving emails due to their reception settings or policies. Additionally, Gmail has experienced similar email reception delays when a large number of emails are sent in a short period following the security policy update on February 1, 2024.
The email server used for this event has already implemented security enhancements and measures to limit the number of emails sent to the same address within a short period to reduce issues. While these steps have ensured proper email delivery, we may still observe reception issues, especially with services like Gmail.
We recommended to either use alternative email services for team registration, or use the above mentioned email services with the understanding that reception may be delayed or unsuccessful.

Please note that we are not responsible for any delays or failures in team registration due to email reception issues or delays.

One of the declared works must be selected for the "FINAL STRIKER" category (hereafter referred to as FS).
The FS work will have special bonus points added to its impression points in the Team Total Points category.
However, FS works are subject to different restrictions than regular entries.

Failure to adhere to these rules may result in the FS work being disqualified.
Additionally, teams that do not select an FS work will be excluded from the team scoring category.

In BOF:TT the Ratio Points System will be reintroduced for the first time since "THE BMS OF FIGHTERS 2005".

Ratio points are allocated differently depending on the number of works:

Ratio points can be assigned at the time of team registration.Changes or reassignments of ratio points can be made until the ratio points change deadline.
If the number of submitted works changes, reassignment of ratio points is mandatory.

Restrictions on Ratio Points:

Bonus points from ratio points are only applied to the Team Total Points category.
They are not included in the calculations for the Team Median Points category or individual score categories.

Team names for this event can be freely changed until the "Deadline to change team name" listed in the schedule.
After this deadline, changes to team names will generally not be accepted.

Team names must follow specific naming rules. Only the characters listed below can be used:

Usage of characters not listed in the above character list is prohibited. This includes languages other than Japanese and English, emojis, characters requiring special layouts, special characters, machine-dependent characters, and control characters.

Teams not adhering to the naming rules will be asked to change their team names by the organizers.
Failure to comply with this request or reaching the team name change deadline without making the required changes may result in disqualification.

Teams can display images that represent their team through banners and emblems during the event.
These images is optional, but if you choose to do so, please adhere to the following guidelines:

Images that do not comply with the guidelines will be flagged by the organizers and may be hidden or deleted.
Repeated submission of non-compliant images, despite warnings from the organizers, may result in team disqualification.

Note: The displayed sizes for team banners and emblems at the event page will be 468px by 60px for banners and 32px by 32px for emblems.

Starting this year, teams can sort the order of their team display using a sorting feature.
This is effective only when the display format is set to "team format"; it does not apply to "list format."

This is the default display format for this year.

When accessing the venue, teams are arranged randomly, irrespective of their registration status, submission numbers, status of submissions, disqualifications, or FINAL STRIKER issues.
This format has the following special features:

・A seed value is generated upon accessing the venue, which is used to sort the teams randomly.
・The seed value is saved in a cookie when accessing the venue, and will not be changed unless the cookie is deleted.
・The seed value can be viewed and changed in the settings menu. Changing the seed value will result in a new random sort.
・Entering the seed value manually in the settings menu allows the same arrangement to be displayed on different devices or browsers.
・Due to its nature, this function does not work in incognito mode.

This is the traditional sorting method used until last year's BOF. Teams are sorted according to the following rules:

・The sum of registration numbers of each BMS (for teams with four BMS, the sum is adjusted by multiplying by 3/4).
・Teams with all tracks registered are ranked by the last registration number. The rank multiplied by 10,000 added to the score. Teams without all tracks are given a fixed rank of 999.
・For each missing BMS, 1,000,000 is added to the score.
Teams are sorted in ascending order of the total score.

Teams with disqualified tracks (excluding FINAL STRIKER issues) are placed at the bottom, regardless of the total score.

Teams are sorted in the order of their registration during the team registration period.
The registration numbers, submission status, disqualifications, and FINAL STRIKER issues are not considered.

(※ The test team "Team Test Registration," used in previous years, will no longer be present from this year due to this ordering scheme.)

This sorting method was used from "THE BMS OF FIGHTERS 2004" to "THE BMS OF FIGHTERS 2008."
Teams are sorted by their names in the following order: symbols, numbers (0-9), English letters (A-Z), hiragana (あ～ん), katakana (ア～ン), and kanji.
The registration numbers, submission status, disqualifications, and FINAL STRIKER issues are not considered.

Only newly created BMS (BMSON) works are allowed to register.
Previously released BMS works cannot be registered.
Any BMS works that are released outside the event venue during the registration period will be considered past works.

Both BMS and BMSON formats are accepted.
The rules generally refer to BMS, but please interpret these references as applicable to BMSON as well.
If so, when registering, clearly indicate that your submission is in the BMSON format.

All BMS (BMSON) works submitted to this event must be uploaded to a storage site, and downloadable by the public. The downloaded BMS (BMSON) files must be playable on either Mocha-Repository version of beatoraja (see )this article for details) or Lunatic Rave 2.
Compress your BMS (BMSON) files in Zip, Rar, or 7-Zip formats.

BMS must include at least one chart for any of the following key modes: 5keys, 7keys, 10keys, 14keys, 9key (PMS), 24keys, or 24keys double.
Hidden charts are considered non-evaluable.

If a chart includes commands that only specific BMS players can execute, indicate this in the work's information.

Include a document listing all contributors when distributing your work.
If you use stock video or image materials, include the site name and URL of the source in the documentation.

BMS works violating any of the following prohibitions will be immediately be disqualified upon discovery:

Additionally, the following types of BMS works may be disqualified at the organizer's discretion:

If a work is disqualified and a solution for reinstatement can be proposed, notification or contact will be made using one of the following methods:

If there is no response within the specified deadline, the work will be disqualified even if there is no issue.

If the content of the disqualified work or the creator's actions are deemed malicious, all information about the work will be deleted, and all works involving the creator will be disqualified.

Disqualified works cannot be reinstated or re-registered, and disqualification cannot be revoked.
Re-registering disqualified works will be considered disruptive behavior, resulting in the deletion of the work information and revocation of participation rights.

※ The items listed in this supplement are not mandatory. Not adhering to them will not result in disqualification.

• When using video files as BGA for LR2, to avoid playback issues with AVI codec, please try to use WMV or MPEG1 (mpg files) as much as possible.
• In BMS, there is a tendency for patterns being high difficulty, and the increase in average difficulty is making it harder for casual users to play the songs. If possible, including beginner (☆1 to ☆3) and intermediate (☆4 to ☆7) level charts would make the songs more accessible for beginner users.
• It is recommended to use only alphanumeric characters for the file names of BMS, audio, and video files. File names using Japanese, Korean, Chinese, or other symbols such as emojis may not be read correctly depending on the OS settings.
• For beatoraja, it is recommended to include a preview file (preview.ogg) and a high-quality BGA mp4 file whenever possible.
• If you have created a BMS using the officially supported base-62 notation in beatoraja, please indicate this in the comments section.
• If you make corrections to your work due to issues or changes/additions to the chart, please add this information to the comments section or include it in the accompanying documentation.

BMS works should basically be uploaded to a web server or storage service such as Google Drive, Dropbox, and OneDrive.
Distribution sites like firestorage, Axfc Uploader, and Gigafile, may be difficult to download from.
Please avoid uploading to file-sharing sites like Baidu that have complex procedures for downloading. It is especially prohibited to upload BMS to sites that demand payment in any form for download.
There are cases where uncompressed BMS works are shared using the folder sharing feature of storage services. Even if there is a function to download as a compressed file, this does not count as uploading a compressed file, and may be disqualified. Please ensure that works are always published in a compressed state.

By registering your work during the event period, you agree to secondary distribution and package distribution by the organizer or volunteers, as long as the archive is not altered. If you cannot agree to this, you cannot participate in this event.
If you cannot agree to this, you cannot participate in this event.

If the distribution guidelines are not followed, or if the download link is not available at the time of registration, the work will be considered non-downloadable and treated as a "pre-registration act".

Regarding the distribution of packages by volunteers, we do not impose restrictions.
However, please note that some tracker sites may only allow distribution of original or authorized copies, arrangements, or remixes. Please be cautious if you are considering distributing packages.

The works planned to be exhibited in this event can be promoted using video and audio formats other than BMS.
However, it is essential to strictly adhere to the following rules:

Works subject to the "FINAL STRIKER" system will be further subjected to specific regulations based on below PR guidelines .

In BOF:TT, the score of a BMS is determined by impressions, which are reviews with score votes.
sers can choose from regular impressions, one-line impressions, or votes (no comment impressions).
The ranking is determined by the total score and the number of impressions for each work (see below for details).

Impressions for this event are for evaluating the work, not for evaluating the personality or behavior of the creator.
The score criteria must be based on the evaluation of the "work as a work," and evaluations "other than the work" should not be included.
When evaluating a work, it must be assessed as a BMS work. Evaluations based solely on viewing the video or audio without playing the BMS work are strictly prohibited.
The BMS player used for evaluation must not violate the prohibited items mentioned later, and as long as it can play the chart included, players other than beatoraja and LR2 can also be used.

When posting impressions, the input of name and email address is required.

Once posted, impressions cannot generally be edited or deleted.
In cases such as "mistaken score" or "accidentally sent the text," please contact the administration via the inquiry form.
However, correction requests for impressions will not be accepted until two days before the end of the impression period. Only deletion requests will be accepted until then.
If the requester's email address does not match the email address of the impression, the deletion request will not be accepted.

You can post impressions composed of multiple lines.
You can assign points ranging from 100 to 1000.
Anonymous and no-comment impressions are not allowed.

This impression format is for those who want to write a simple review.
You can assign points ranging from 100 to 1000.
Anonymous and no-comment impressions are not allowed.

If you perform a one-line impression with no comment, it will be considered a vote.
Voting is reflected in the number of impressions and points but is not shown in the headline.

Please refrain from posting evaluations using comments before the impression period begins.
The comment function before the impression period starts is only open for reporting issues with the works.
Any posts other than this purpose will be considered fraudulent and deleted.

Impressions based solely on audio or video viewing will be deleted.
Please ensure that you use a BMS player to play and evaluate the work as a BMS.

Due to system constraints, impressions via smartphone or tablet, and impressions through anonymous browsers such as Tor, are prohibited.
Please use a PC to post impressions.
You can only post comments without scores from smartphones and tablets.
impressions with scores posted from smartphones and tablets disguising as PC will be invalidated. Repeat offenders will have all their posts invalidated.

Player scores are tallied based on impressions written or votes cast.
Each team's rank in the respective categories is determined by the total score of their works.

The median value of the impressions would be used to determine the outcome for this category. Only teams that have submitted the declared number of works are included in the median aggregation.
Score adjustments through the Ratio Points System and the FINAL STRIKER System are not applied in this category.

In this category, the total impression points from all impressions are calculated, and teams are ranked based on this total.
The more evaluations a team receives, the higher their ranking. Additionally, points for each work are added through the Ratio Points System and calculated with the formula mentioned later.
The FINAL STRIKER System also applies in this category, where points for works designated as FINAL STRIKER are added according to the specified formula.

As a reference, a separate aggregation will be conducted for individual songs, regardless of team affiliation.
These categories are for reference only and do not affect team rankings.

Similar to the Team Median Category, this category aggregates based on the median value of impression points for each song.
Score adjustments through the Ratio Points and the FINAL STRIKER System are not applied.

In this category, the total impression points for each song are calculated, and songs are ranked based on this total.
Score adjustments through the Ratio Points and the FINAL STRIKER System are not applied.

This category is for player participants rather than team participants.
It recognizes players who have written many impressions for event entries, ranking them based on the total number of qualifying impressions they have posted.

The Tripkey function, which displayed an encrypted ID by adding a half-width sharp (#) to the name, has been abolished due to frequent issues with Unicode characters.
The "Tripcode" feature replaces the tripkey function. Note that after adding a half-width sharp, subsequent characters will not be converted.

When you enter characters in the "Tripcode" field, the characters following the sharp are automatically converted to an encrypted ID (the part after ◆).
The tripcode is a feature for those who want to prove they are the same person while hiding their name, or for those who use different names for different works.
Although simple strings (about 4 characters) can be converted, they are likely to be duplicated, so it is recommended to use longer characters.
For more details, please check our post about it.。
