100 levels of 4 rounds each. Every round shows three true statements and one confident lie about the same subject. Call the fake, learn the hallucination pattern behind it, and play every round. Levels clear at 75% accuracy; a boss guards every twentieth level, and only the final boss demands a perfect run.

How to play

Hallucination Hunt

Every round shows four statements about one subject. Three are true. One was hallucinated by an AI: plausible, confident, and wrong.

Scroll to see all 3 steps

  1. Step 1

    Read all four

    The fake is engineered to blend in: right vocabulary, right tone, wrong fact.

  2. Step 2

    Call the fake

    Select the statement you suspect and lock it in. Every round is played. Catch at least three of four to clear; only the final boss requires all four.

  3. Step 3

    Learn the tell

    Every reveal names the hallucination pattern. Score combines accuracy with a streak bonus: 3/4 earns 75 or 80, and 4/4 earns 100. Normal levels and checkpoint bosses clear at 3/4; only the final boss needs 4/4.
