Theme: Logical
Author/Opus: This is the 322nd puzzle from Thomas Snyder, aka Dr. Sudoku.
Rules: Variation of Battleships and Yajilin. Place the fleet of ships in the grid so that no ships touch each other, even diagonally. The grid contains internal clues (a number and an arrow) that show how many ship segments are in the indicated direction. All remaining white cells that do not contain a ship segment must be able to form a single loop, as in a Yajilin puzzle.
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 = 1:30, Master = 2:30, Expert = 5:00
