I think I'm slowly getting the hang of these. But they require a solving technique different from the other puzzles.
Instead of CP-based techniques (domain reduction through constraint propagation, and "shaving" for the hardest puzzles), I'm using Local Search: make an initial guess based on "feel" and then repair it through local changes.
Works surprisingly well in many cases, though there's a danger of missing some non-linked shaded areas.

You're right. That's partly a factor of how I've designed these particular nurikabe, however. Many nurikabe, particularly larger ones, can be solved in a more step-by-step process. However to keep the 10x10 ones interesting I've heavily used a 'make it fit' type of design for the ones here.

That explains a lot ;-) Lots of 10x10s - how many of other sizes are on hold?

They're virtually all 10x10.

Oh, ok. At the beginning of their reappearance we had some larger ones. So I wondered if there was more of those. Thank you for bringing them back!

Yes, it's a fair question. That was just by chance. I've taken a look and I have two 12x12 and one 15x15 queued up, and that's it in terms of puzzles > 10x10.
If anyone out there fancies writing some nurikabe then I would consider buying them - particularly larger ones. However I should say this is not going to get you rich... Get in touch if interested - gareth@puzzlemix.com

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
Instead of CP-based techniques (domain reduction through constraint propagation, and "shaving" for the hardest puzzles), I'm using Local Search: make an initial guess based on "feel" and then repair it through local changes.
