Mr. Mysto

A word-guessing game that learns as it plays. Think of a word and answer Mr. Mysto's questions YES or NO, and the bearded mystic tries to guess it. When he is right he says so; when he is wrong, you tell him your word and type a question that tells it apart from his guess, with the answer for your word, and he never misses that word again. Start a new category from nothing, try a small ready-made set of animals, or continue with what he has learned this session. His face talks and his eyes follow the cursor as he speaks. He remembers up to 60 words until the power goes off, then says his memory is full.

Controls: Use either joystick. The stick moves the cursor over the on-screen keys (hold to repeat); the left button presses the key, and the right button deletes the last letter. Answer YES or NO with the stick and the left button.
