Bomb Word Chain Terms of Service

Established: October 29, 2026

These Terms of Service ("Terms") are the rules for using "Bomb Word Chain" (Bakudan Shiritori; the mobile apps and the web version, "the Game") provided by Koofunnel ("we"). By using the Game, you agree to these Terms. If you are a minor, please get your parent's or guardian's permission first. If the Japanese and English versions differ, the Japanese version prevails.

1. Prohibited conduct

We have zero tolerance for objectionable names or words and abusive behavior. We review reports promptly and may remove names or ban players.

When using the Game, you must not:

  1. Use inappropriate names or words, such as hurtful, obscene, discriminatory or violent ones
  2. Put information that identifies you or others (real name, address, phone number, etc.) in names or words
  3. Pretend to be another person or organization
  4. Disturb other players, for example by stalling games on purpose, repeatedly leaving mid-game, or targeting the same person
  5. Repeatedly make false reports
  6. Interfere with the Game, such as modifying the program, using cheating tools or attacking the servers, or raise your rating unfairly
  7. Break the law or act against public order and morals
  8. Do anything else similar to the above that causes trouble for other players or for the operation of the Game

2. What we may do

If we decide that a player has done anything in section 1, we may, without prior notice:

We may not be able to tell you the reasons for these decisions.

3. One-time purchase "Premium"

4. Changes and interruptions

We may change the Game or pause it for maintenance without prior notice. Online play may be unavailable because of network or server conditions.

If we stop providing the Game, we will, in principle, announce it in the Game and on this page at least 30 days in advance.

5. Disclaimer

6. Rights

The rights to the Game's art, sound, program and text belong to us or their rightful owners. Dictionary sources are listed under "Credits" below.

7. Personal information

How we handle your information is described in the Privacy Policy.

8. Changes to these Terms

We may change these Terms in accordance with the Civil Code of Japan. When we do, we will announce the changes and the date they take effect on this page (and, for major changes, also in the Game) before that date.

9. Governing law and court

These Terms are governed by the laws of Japan. Any dispute about the Game shall be subject to the exclusive jurisdiction of the district court or summary court with jurisdiction over our location as the court of first instance. However, this does not limit any rights or choice of court you have under the laws of the country where you live.
