15 October 2026 · A new Archive

Ostraka starts afresh, with a new daily game:

• One investigation a day: a memory has disappeared (a place, a work of art, a famous person…). Three short workshops bring out its traces; it's up to you to recover it.
• Crests: Gold if you find it with a single trace, Silver with two, Bronze with three.
• A collection: every memory you recover gives you its card, with what it really was and an anecdote on the back.
• The archives: past days can still be played, to catch up on a missed one.
• No account needed: you can play straight away; to keep your progress across devices, an email address is enough, with no password.
• Reminders, if you want them: a notification every morning, or an email after a few days away.
• Achievements to unlock, and avatars to pick in your profile.
• In French and English.

The previous version of the game is making way: its accounts and progress are not carried over.
