Theme: Field Goal

Author/Opus: This is the 2nd puzzle from guest contributor Fidel Zapico.

Rules: Place either 0, 1, or 2 mines into each empty cell so that each number represents the total count of mines in all neighboring cells, including diagonally adjacent cells. See also this example:

Answer String: For each cell in the marked columns, enter the number of mines (0, 1, 2) for each cell. Enter 0 if the cell is a number cell. Separate each column’s entry from the next with a comma. In the example (with marked rows), the answer is “022102,002000”.

Time Standards (highlight to view): Grandmaster = 2:45, Master = 5:15, Expert = 10:30
