Minefield was published in 1984 for the Commodore 64 by P. K. McBride.

Here's a game that uses the screen and colour memories. The object of the game is to reach the bottom right corner, without treading on a mine. It's a bit bare at the moment, so that you can see the main routines more clearly. When you've got it running, you might like to improve the presentation and add some sound effects. I have used asterisks (code 42) to indicate mines, and a blob (code 81) to show the player's position.

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.
