Prediction Game

Outguess

Try to be unpredictable. A tiny AI predicts your next key press — and catches humans about 70% of the time.

Each tap is one trial. Predictors guess the next tap before it happens.

Why?

Internal state of the leading predictor (—).

Not enough history yet for to anchor a context.

Why this works. An order-5 Markov chain catches human key-tapping ~70% of the time because humans systematically avoid repetition when trying to be random. Hide the AI guess to play a fair test of your own randomness, and watch the lifetime tally to see how the leading model is doing across the whole session.
