Minefield was written in 1984 for the Commodore 64 by Derek Waldron.

Sapper Sid has been left in charge of a group of men whom he must guide back to safety. Unfortunately all the fields between him and home are mined and he is in charge of the one remaining mine detector. Even more unfortunate is the fact that the detector is not 100 per cent reliable. It will warn him when there is a mine within one step of his present position, but it won't tell him in which direction. Armed with this knowledge, he (you) has to find his way safely across each of the fields he comes to. He does have one trick up his sleeve which quite often proves invaluable, namely a mine detonator. This device, when used, will detonate all the mines that are currently being 'detected' by the mine detector. The only drawback of this device is that it may only be used once in any field. Sapper Sid starts each field in the bottom left corner and must find his way to the top left corner. The first field contains ten mines and five more are added every other field. To get a high score, I recommend that as many of the earlier fields be cleared as possible, as the later fields become a pure test of survival! If the number of lives remaining is getting low, it usually proves best to try and complete the field to obtain an extra life. Also, if you find that you can complete a field without having to use the detonator, go back and use it where it will give you the most points. You cannot carry an unused detonator into the next field. Instructions to play the game are contained within the program, including which keys to use for movement.

You have 5 lives to cross a 10*8 minefield from the bottom left corner to the top right corner. The mine detector works vertically and horizontally and you can move up [W] down [Z] left [A] and right [S]. Pressing [Space] will detonate one adjacent mine but this can only be used once per level. The points are 5 for a mine, 10 for an opened cell and 50 for completing a level. Each new level awards one more life.

The following attributes can be used to map the evolution of Minesweeper. Blue cells are confirmed attributes for official versions of Minefield. Yellow cells are unknown.
