The Mind Reading Machine


This game is a replication of Claude E. Shannon's Mind Reading Machine that he developed in the 1950's.  The machine competes with a human player in a game of chance.  You can find Shannon's original paper here.

The human player selects heads (H) or tails (T). But before the human plays, the machine guesses what the human is about to play.  If the machine guesses correctly, it gets a point, if not, the human gets a point.

The player who gets to the target first wins.

The Auto Play button lets the machine play a set of random choices against itself.

Target Value:


Heads Tails Reset Auto
