The museum of guessing
Think of a historical event. Answer yes or no, and the AI closes in, usually in under fifteen questions. How did it know?
Free. No signup. Just you and the machine.
How it works
Step 1
Anything from the fall of Rome to the moon landing. Don't say it out loud. Just hold it.
Step 2
The Guessarium asks. You answer with one of five chips.
Step 3
The needle narrows, the dial locks, and the answer engraves itself. Then you share the score.

The live ledger
The collection count is live. The win rate turns on after 30 finished games, and the question average after 30 wins, because a rate built on a handful of rounds is noise. We'd rather show you nothing than a number you shouldn't trust.
For teachers
No accounts. No student data. Ever. Pick a unit and the whole class plays, or flip to Reverse mode where students do the asking and practice real historical thinking.
The class thinks of an event from the unit. The AI interrogates. Instant review.
The AI hides an event. Students ask the yes or no questions. Inquiry, gamified.
Every event is reviewed by the Guessarium editorial team before it is published. How that works.
Play as much as you want. There's no paywall and nothing interrupts a round.
Guessarium is entertainment. It doesn't read minds and it isn't a quiz app in disguise.
More from the museum is coming: Huminator for songs, DreamDeducer for dreams, Placesleuth for places, and Guessona for personas. None of them are built yet.
