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

  011--1?????????
  12*101?????????
  ??2211?????????
  ???????????????
  [6 rows clipped]
  + 29 mines left to find becomes

  011--1-????????
  12*101-????????
  ??2211*????????
  ????---????????
  [6 rows clipped]
  + 28 mines left to find)

Dashes seem to be places that might be a mine but also might not (because the game has to reserve the right to move mines around depending on where you click).

In this case it's telling you that 6 over (zero indexed) and 2 down (the spot is marked with an asterisk in the second diagram) is safe, because of the pattern of "ones" on the left edge.
