Magic Boxes

A mathematical game with a twist: you are given a four by four equation
lattice with the symbols and numbers missing. Your job is to fill in the
squares so that all the equations across and down are correct. You have a set
of numbers and symbols at the bottom of the screen that you can choose from
and as you use them they disappear from the bottom of the screen and appear in
the boxes you assign them.

The Apple II version of this game has hi-res graphics. The PC version of this
game was John Romero’s first PC game ever and was written in Pascal while the
game display was done in colored text mode.
