Theme: Xs Mark the Spots
Author/Opus: This is the 324th puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Variation of standard Battleships rules. Instead of exterior clues, clues inside the grid indicate the number of adjacent squares, including diagonally adjacent squares, containing ship segments. Ships do not sit on cells with numbers.
Answer String: For each row from top to bottom, enter the number of the first column from the left where a ship segment appears (enter just the last digit for any two-digit number). If the row is empty, enter 0. Enter these numbers as a single string with no separators.
Time Standards (highlight to view): Grandmaster = 3:15, Master = 5:00, Expert = 10:00
