This game received a 4/5 rating in Sweden's late (sob) DMZ magazine.
It's a non-violent, educational thing which at the same time succeeds 
in being quite interesting and fun to play. 

It's a two player game where the computer can play as none, one, or both
players. There is also lots of other stuff to set up and adjust to suit 
your taste.

The author takes no responsibility for brains overheating as a result 
of playing. However, if you do survive, your mathematical skills will
be polished to perfection!
