A relatively minimalist Sudoku-Suguru-Nurikabe hybrid this time around, hope you enjoy! Should be relatively approachable.

Rules:
Sudoku: Place the digits 1-9 to each row, column and outlined 3x3 box without repeats.
XV Pairs: Digits separated by an X sum to 10. Not all X'es are given.
Suguru / Nurikabe: Shade some cells in the grid such that all the following conditions are fulfilled:

  • All shaded cells are orthogonally connected, without creating a 2x2 area.
  • Groups of orthogonally connected unshaded cells form islands. Each island has exactly one circle, and the number in the circle shows the size of the island.
  • Each island contains digits 1 to N without repeats, where N is the size of the island.
  • Each island is of different size.

Puzzle Links: You can play this puzzle in either F-Puzzles or in the CTC Software.

Very lovely puzzle. Flows nicely and lots of fun!
Shading was pretty straight forward, but still had some tricky arts where it was necessary to ask the right questions.

Very nice! Fun and smooth solve path with a lot of nice interactions, but no places you needed something crazy to get on. Really liked this. Thanks!

Fantastic set! And fantastic solve! The path was very intricate but deductions came smoothly. Thanks

don't think it was listed in rules, all unshaded cells are part of islands

Plenty of fun and satisfaction! Quite a bit disappointing that the 'treasure' was buried at such terrible place :P

Does the X mark the spot of the pirates treasure ?
Well done, Captain Niverrow !! Thanks :)

Surely one of the best Nurikabe-Sudokus I ever had the pleasure to solve! Thank you so much for setting and sharing this wonderful gem.

I had lots of joy solving this one, and the ending was spectacular! Thanks!

This was a very satisfying solve. I got stuck after the initial bit, but I think it's because I don't do many of these shading puzzles that often, even though they end up looking so pretty!

Wunderbar! Enjoyed this a lot. That lonely X, tho …
Thanks for this puzzle, Niv!

Very nice and very satisfying. It appears there is no rule barring circles in unshaded cells, only that islands must have a circle. While I assumed all circles were in an island and found the solve, I also found solves where circles were in the ocean while obeying all other rules. Did I miss some logic there?

Sterling setting Niverio! Sudoku-Suguru-Nuribake is the hybrid I didn't know I needed until right now.
