classic game, similar to Mine Sweeper, MindField has you hunting
for happy-face mines. You must find them not by clicking them
(oh no, that would blow you up!) but instead you find all
clear areas around them.
Squares with numbers are hints that tell you how many adjacent
mines there are (either to the left, right, top or below the
square with the number). So for example, a square with a 2
on it has a mine adjacent to two sides of it. The question
is, where exactly are they?
If you are pretty sure where a mine is located, you can mark
that square with a flag (and get points for it) by holding
the CTRL key while clicking the square.
