1. Entertainment purposes only

WhenBorder is a trivia game, not an academic or reference source. The border years and historical clues used in the game have been curated and simplified to fit a quick daily quiz format, and may not always reflect the full nuance or latest scholarly consensus on a given historical event.

2. Possible inaccuracies

In particular:

• Some borders changed gradually or were disputed, so picking a single "last year in use" is necessarily a simplification;
• Historical clues are short summaries and may omit context or nuance;
• Dates, names and territorial descriptions may occasionally contain errors.

3. Not a source of truth

Please do not treat any date, hint or fact shown in the game as authoritative. If you need accurate historical information, verify it independently with a reliable, up-to-date source (e.g. an academic reference or encyclopedia).

4. Feedback

If you spot an error, feel free to let us know at info@whenborder.com.
