You take the part of a child who has foolishly entered the ghastly grammar school and fallen into the hands of the ghosts. You go from room to room and in each room, the master asks you three questions on his subject.
Should you fail any of them, he gloatingly tells you the answer and back to the beginning you go. But only after the ghosts have taunted you about your stupidity!
It's amusing and becomes compulsive. All the usual school subjects are covered and there's a fair selection of questions. It's the kind of game that kids love - not just playing it themselves but also watching others make mistakes and get insulted. And they're learning all the time.
The program is fun and original. No doubt educationalists will say that it just teaches facts, not understanding, but that's just a quibble. The program is amusing and addictive. In fact it's magic.
