Theseus and the Minotaur is a series of Java-based puzzles in which you have to escape a maze without getting mashed by a computerized monster that moves predictably. There are 14 levels, and I can’t get past level 4.
The interesting thing is that the puzzles were designed by a computer, and they’re now being used in AI experiments at the National University of Ireland. So computers are now solving puzzles designed by other computers.
