Today I played the Memotech version and it seems the Einstein version is bugged. You should find the ring by typing LOOK CUP, but that does not work with the Einstein Version.
Unfortunately it seems the Memotech version like the Einstein version also contains one bug. You don't get a point for dropping the bag of diamonds making it impossible to end the game.
