Minefield was written for the VIC 20 in 1985 by Paul Randall.

Minefield is a program based around a very simple idea. All you have to do is cross the minefield, but this is not as easy as it may first seem. For a start, all the mines are hidden. The solution for this is obvious - get a mine detector. Unfortunately, yours is defective. While it will tell you how many mines surround you, it won't tell you where they are. You've got to work that our yourself. The only help you've got is the fact that as you move over a square it is filled in. This means you can see the "safe" areas.

Incidentally, if your detector (top left corner) reads safe, that means there are no mines either up, down, left or right. To move, enter U(p) D(own) L(eft) R(ight). Head for the H and once you've made it (or been blown up) you'll get a chance to review your moves with the mines on the screen (no, you can't change a move!). This can be very revealing. There are six levels, each higher level adds 25 more mines. Good luck!

The H (home) location changes with each game.
