Theme: Consecutive Partners

Author/Opus: This is the 8th puzzle from guest contributor Murat Can Tonta.

Rules: Shade some dominoes (pairs of empty cells) black so that each number indicates the total count of white cells connected vertically and horizontally to that number including the numbered cell itself. Dominoes cannot share an edge, and all white cells must belong to a single connected group. Or see this example:

Answer String: Enter the length in cells of each of the white segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. This example has the key “23,15”.

Time Standards (highlight to view): Grandmaster = 4:00, Master = 5:30, Expert = 11:00

Note: Kuromasu is a new puzzle for us this week and we are curious to hear what you think of it.

Nice puzzle. 🙂

I find it interesting how much the use of dominoes instead of singletons modifies the logic needed for the solve.
