From the Foxger’s Den #58: Battleships (Nansuke)
or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between ship placement, shading, and number entry modes. In ship placement mode, right click gives sea, left click gives circle/square, left click and drag for rounded ships.)
Theme: Logical
Rules: Hybrid of Battleships and Criss-Cross (Nansuke) puzzles:
Place the given fleet into the grid so that no two ships touch, even diagonally. In the remaining unused cells, place the given numbers criss-cross style so that they can be read from left to right or from top to bottom. All possible entries with two or more connected digits are given.
Answer String: Entry the contents of the two marked columns from top to bottom, using a capital X for any cell with a ship segment.
Time Standards (highlight to view): Grandmaster = 4:00, Master = 10:30, Expert = 21:00
Solution: PDF
I like this variation.
This puzzle is really hard if you forget about that top bottom left right rule… you can get surprisingly far without it though 😉
