Minefields was published for the Microbee by PRIMUG.

"You are required to cross a mine field. The object is to reach the bottom right corner, and visit as many squares as you can without being blown up. You have a mine detector which prints the number of adjoining squares which have mines, but does not tell you on which squares. Enter the number of mines you wish to dodge. (10 is easy, 40 is hard, 100 is almost impossible)."

One interesting feature is that the direction controls on the number pad (on a modern computer) are upside-down, so the arrows that point toward you move the character away. The score is the number of opened cells but there is no highscore list.

Minefields was written by P. Atkinson, modified by Chris Welsh and published in 1983 on a PRIMUG public domain software cassette. Side A contained Bcopy2, Spelling Tutor 3, Build an Equation, Camel, Minefields and Odd One Out while Side B contained Assignment 46 and Mugwump. It was written in MicroWorld BASIC.
