Author/Opus: This is the 293rd puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Place a mine into some of the empty cells so that each number represents the total count of mines in neighboring cells, including diagonally adjacent cells.
Answer String: For each cell in the marked rows, enter a 1 if it contains a mine and a 0 if the cell is empty (or a clue cell). Separate each row’s entry from the next with a comma. The format will resemble “0010101000,1110010101,1000011011”.
Time Standards (highlight to view): Grandmaster = 0:50, Master = 1:15, Expert = 2:30
