Java Edition
“New Game” button creates a new game. The “Continue” button loads the progress from a selected “progress” file. The “Save Progress” saves progress to a selected “progress” file. “Save Board” saves the mine placement to a selected board file and resets. It does not save progress. “Load Board” load the mine placement from a selected board file resets. The “Reset” button resets by restoring question marks, “Spaces Checked” count, “Mines Left” count, and removing flags.
In “Sweep Mode”, clicking a question mark spot reveals a mine, blank spot or number. “Flag Mode” allows marking areas the user believes are mines. Clicking a mine in “Sweep Mode” loses the game (although, the “Reset” button can undo this)
The images from my original article are missing. I plan to replace them soon.
