Theme: Logical

Author/Opus: This is the 262th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: (Combination of Minesweeper, Double Minesweeper, and Statue Park rules.)

Place each of the tetrominoes exactly once into the grid, with rotations and reflections allowed. No two tetrominoes can overlap or be orthogonally adjacent. Each cell in the tetrominoes is given a numeric value, and the numbered cells in the grid indicate the count of the values of the tetromino parts in all surrounding cells (including diagonally adjacent cells). Numbered cells cannot contain tetrominoes, and all of the space not occupied by tetrominoes including any numbered cells must be connected.

Answer String: For each cell in the marked rows, enter the total value of tetromino pieces present (1 or 2) for each filled cell and 0 for any numbered cell and any empty cell. Separate each row’s entry from the next with a comma. An example answer string is: “0220111102,0110220200,1102220102”.

Time Standards (highlight to view): Grandmaster = 3:45, Master = 5:15, Expert = 10:30
