Fata Morgana
An online observation challenge in which you learn to recognise AI hallucinations.
:focal())
AI assistants like Copilot are powerful, but sometimes they hallucinate: they generate text that sounds convincing yet is factually wrong.
Fata Morgana is an individual challenge that sharpens your critical eye. You travel through a mystical desert landscape, read ancient scrolls, letters and consultations with an oracle, and uncover the invented passages before the parchment disappears into the sand.
Programme
1
Read the documents: every scene shows scrolls, letters or consultations that may contain a hallucination.
2
Spot the mirage: click the passage you think AI made up. Is everything correct? Then click the checkmark.
3
Keep an eye on the timer: documents fade over time. Read carefully, but do not hesitate too long.
4
Complete all 5 scenes: the challenges get harder each time. Try to unmask every illusion.
5
View your results: at the end you see your total score, your accuracy percentage and your rank.
You learn to recognise AI hallucinations in realistic-looking documents
You play against the clock: documents fade if you wait too long, so you decide quickly whether a text is right
Sometimes a document is entirely correct, and then you tick the checkmark
The more accurately you play, the higher your rank, with Mirage Hunter and Fata Morgana Master as the top levels
