Cool concept, matches how I want to play Mindsweeper (though others are pointing out some interesting parts of the game that this approach removes).

Played through it once and was confused by why a bomb exploded. Can somebody help me interpret? I'm especially having trouble figuring out what the dashes are in this end-of-game explainer text. Take the space diagonally top-right from the one flagged bomb (the asterix). This had a visible "1" on the board, but is marked as a dash here.

Made a mine because the user clicked it when there was a safe space at 6, 2. Can't be a mine because

  12*101?????????
  ??2211?????????
