A game of the infamous "Cassette 50" collection. This game collection taught so many youngsters so very much: not to trust advertisements, if it looks too good to be true it is probably worse than you can even imagine, that sort of thing. This game screams DO YOUR SUMS! Then asks for your name and age and if it can play with you. If you say yet it will start you off with sums. If you get the sum correctly it'll draw part of your house, if you make a mistake it will draw part of the computer house. Press I after entering your answer, if you make a mistake press M and you can do it again.
