Thankfully the game works with just the regular number row, so my only comment would be to update the instructions to say so. Other than that, a great game for quick thinking and also practicing my number typing :)
Absolutely fascinating twist on minesweeper! I love that hitting a monster on your first few clicks--which are always purely guesswork--isn't an automatic lose. Thanks to all the commenters w/helps too :)
