Prediction Game
Outguess
Try to be unpredictable. A tiny AI predicts your next key press — and catches humans about 70% of the time.
Arena
Each tap is one trial. Predictors guess the next tap before it happens.

Prediction by Partial Matching, max order 8 with escape blending.

Conditional bigram entropy of your input. The lower it goes, the more patterned you are.
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.
