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'.
