Date the Globe — a daily map-dating puzzle

">

Daily map file

One real map.<br>Its date, redacted.

Every day the archive releases a genuine historical map with the dates<br>blacked out. Read the names on it — empires, colonies, countries that no<br>longer exist — and pin down the year of publication in six guesses.

Evidence after each miss, the archivist files one name from the map as evidence — open the file entry to see what it proves.

Direction every miss says whether the true year is earlier or later.

Temperature hot within 2 · warm within 9 · cool within 24 · cold beyond.

How to play

The map is real; only its dates have been redacted. Guess the year it was published — you have six stamps, between 1900 and 2025 .

Study the map. Countries appear and vanish; every name printed on it is a dating clue. (A pre-extracted names sighted list is tucked under a toggle if you want the help.)

Stamp a year. If it’s wrong, the archivist files one name off the map as evidence — a name that contradicts your year (a country that didn’t exist yet, say), or, when every name fits it, one whose era of use narrows the field. It stays sealed in the examination record until you choose to open it.

You’ll also learn the direction (earlier / later) and the temperature : hot within 2 years, warm within 9, cool within 24, cold beyond.

The century ruler keeps the bookkeeping: hatched stretches are ruled out.

Land the exact year to solve the file. A new map opens at midnight.
