This teaches subject vocabulary and knowledge with a question and answer-based approach. Each answer must be given by choosing which of the given letters is correct, using hand-eye co-ordination to answer as quickly as possible.

The game:
The zombies are alive, and looking for young brains! As each hand emerges from the grave, it will hold a letter. If this letter appears in the answer (you do know the answer to the question, right?) the zombie will disappear back into the ground, and you'll be safe. If not, a little piece of your brain juice will be eaten. If they feast on too much of your brain, the game will end. And you'll become a zombie, too!
