Battleship Sudoku by Serkan Yürekli

PDF

or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between number placement, ship placement, and shading modes. The shading mode in gray, which numbers can be written on top of, may work better than default ship placement.)

Theme: Dominoes

Author/Opus: This is the 370th puzzle from our managing editor Serkan Yürekli.

Rules: Standard Battleship Sudoku rules. This combines Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region) with Battleship rules: Locate the given fleet, as in a Battleships puzzle. Each ship segment is numbered and these numbers must fit into a valid sudoku solution as well. Ships can be rotated when positioned in the grid, but different ships cannot be placed in adjacent cells that share an edge or corner. The clues outside the grid indicate the number of ship segments in that row/column. Numbers inside the grid at the start should be treated like “seas” and cannot belong to ships in the fleet.

Difficulty: 5 stars

Time Standards (highlight to view): Grandmaster = 20:00, Master = 55:00, Expert = 1:50:00

Solution: PDF and solving video.
