Atlas is offered free for learning and entertainment. You may play in a normal browser and share a link to the site.

We write and edit our own question wording and explanations, but mistakes can occur. The game is not an authoritative historical or geographic reference. Please use the Contact page to report an error.

The map is illustrative. Your progress is stored in your browser and can disappear if you clear site data or change devices.

Ads are served by third parties under their own terms and privacy policies; Atlas is not responsible for the content of external advertisers or linked sites. Question wording and explanations are our own summaries, not authoritative references.
