Minefield was published in 1984 for the Oric by Wynford James.

In Minefield you have to find your way across a minefield riddled with potholes. You have a little help from your mine-detector, but its batteries are limited, so you must be decisive.

The mines on the field are randomly placed at the start, and their positions saved in the array M( ). Whenever a move is made, all nearby mine positions are examined, line 130, and checked to see if they correspond to positions directly surrounding the little man the player controls. The number of mines around the present spot is then displayed on-screen, although the player will have no idea in which direction the mines lie.

By comparing the number of mines surrounding one position to another adjacent spot, it is sometimes possible to deduce the mine locations. When this proves difficult, backtracking to a less dangerous path may be wisest, or you can always take the risk!

A trail of markers is left to show the safe path.

You win by navigating to the top left corner. There are 10 difficulty levels with 11 to 20 mines. You lose by hitting a mine or walking into a visible pothole.
