Nurikabe by Grant Fikes
or solve online (using our beta test of Penpa-Edit tools)
Theme: Stanyon Count (The Stanyon Count, a variation of and predecessor to the Elmsley Count, is a card sleight in magic tricks that makes 3 cards appear to be 4 cards; in this puzzle, 3 can become 4 and still be solved.)
Author/Opus: This is the 110th puzzle from our contributing puzzlemaster Grant Fikes.
Rules: Standard Nurikabe rules. There are two puzzles to solve.
Answer String: Enter the length in cells of each of the black segments (the unnumbered, connected “ocean”) from left to right for the marked rows, starting with the top grid and then the bottom grid. Separate each row’s entry from the next with a comma.
Time Standards (highlight to view): Grandmaster = 2:00, Master = 3:30, Expert = 7:00 – Note these time standards are for finishing both puzzles.
Solution: PDF

Nice pair of puzzles, with different flavors, particularly regarding the 11.
There should be a puzzle pair where the second puzzle is the first puzzle with givens incremented by 1. Pretty sure there’s some out there…is there?
…oops this already has two increments. What about an incremented Nurikabe?
…and this one
http://nbpuzzles.wordpress.com/2013/12/07/slitherlink-2-cyclic/
has infinitely many increments, albeit modulo four.
Also, the comments for those two have some incremental Skyscrapers.
I made one Fillomino where you can double all clues and still have a unique solution, but it is very small:
– – – –
– – – –
– 1 6 –
– 6 1 –
I don’t know any other puzzles with this sort of arithmetical twinning. Does anyone?
