Terms of use

Version 2026-11-12. Riddle Dive 採掘 is a free game for practising Japanese vocabulary, run by Alex Chiarini. By creating an account or playing, you agree to these terms and to the privacy policy.

Playing and accounts

Display names

Your display name is public. Do not use a name that is offensive, impersonates someone, or contains another person’s private details. We may change a name or hide an account from the leaderboard without notice.

Fair play

The leaderboard is for fun. Do not use scripts, bots, edited requests or bugs to gain points. We can reset points, remove accounts from the leaderboard, or close accounts that do.

The learning material

The word lists, readings and translations come from third-party sources (see Credits) and the riddles and example sentences are written or assembled for this game. They can contain mistakes and some example sentences may sound unnatural. Check anything important with a teacher or a dictionary.

Our property and yours

The game, its code, artwork and sounds belong to Alex Chiarini or are used under licence. You may play it, but not copy, resell or scrape it. The third-party data keeps its own licences. You keep ownership of your display name; you give us permission to show it in the game.

The service

The game is provided free and “as it is”. We may change it, pause it or close it, and we will try to give notice and a way to download your data first. We do not promise it will always be available or error-free.

Tips

The game is free. If you would like to support it, you can leave a tip through ko-fi.com. A tip is a voluntary gift: it buys nothing in the game and does not change your rank, your points or your account. The payment is handled by that service under its own terms. To ask about a tip you sent, including a refund, write to us at alxchiarini@gmail.com.

Liability

Nothing in these terms limits liability that cannot be limited by law, such as for death or personal injury caused by negligence, or for fraud. Subject to that, we are not responsible for losses that were not reasonably foreseeable, or for loss of game progress or points.

Ending your account

You can delete your account whenever you like from the account screen. We may suspend or close an account that breaks these terms, and we will tell you why if we reasonably can.

Changes

We may update these terms. When we do, we will change the version date above and, for important changes, let you know in the game or by email. If you keep playing after that, you accept the new terms; if you do not agree, you can delete your account.
