A guessing game by John S. James

Flip is a very simple computer game by John S. James which first appeared in the March/April 1977 edition of Creative Computing. In the game, the computer flips a virtual coin 50 times, and the object is for you to guess whether the coin will come up heads or tails each time. What makes it interesting is that the coin is not fair. The computer tries to find patterns in your guesses, and exploit them by biasing the coin toss away from what it thinks you are likely to guess next.
