Mine sweeping (Posted on 2006-04-11) Difficulty: 3 of 5
In the popular game of Minesweeper, the object is to find all the mines. If you click on a square it shows a number from 0 to 8 indicating how many of the adjacent squares contain mines. If you click on a mine, you lose.

Can you figure out where the mines are in the below board? Blank squares indicate that it is unknown whether there is a mine in that space. Squares with numbers contain no mines (or you would have already lost).

(In reply to Solution by Kevin K-C)

Your solution is incorrect - the 2nd "2" in the top row is only touching one mine.  I ran into the same thing earlier, so I recognized it right away.  This puzzle is driving me nuts!  I'm starting to think it's impossible...
