    Yes, this is the first Double Minesweeper I’ve ever done, I think. Still figuring out the best way to do this on MS Paint. Nice puzzle!

      I used the circle shape to draw the mines, and flood-filled all completed squares in a light color. It seemed to work fairly well for me.

    • Paul K says:

      I just used a thick brush. Made a dot in the top of the box for a mine, drew a short line across the bottom of the box when complete.

  • Andrew Brecher says:

    I just used numbers — no dots, except to temporarily mark a cell that had either 1 or 2.
