Much easier than Jotto, the pen-and-paper word version of Mastermind I've played since the 60's. In Jotto, you get told if *a* letter is in the right place, but not *which* letter. For instance if you guessed STERN for my word STORK I would say 3 in the right place, none in the wrong. If you guessed MOCKS I would say 3 in the wrong, none in the right.
