This is a 1.5-star Unknown Nurikabe II; that is, a Nurikabe II puzzle with the Unknown twist. Some objects have less meaning than it should be. In this puzzle, one given is not placed, and it’s value is unknown. It’s up to you to determine where the given would be placed, and what value it should be. The solution is not necessarily unique...or is it?
S003 - Nurikabe II (Hidden)
Whoa?! An unknown clue in Nurikabe?! What could that be? And why the rating is only 1.5 stars? Something is suspicious here…
A Chaotically Puzzling Blog 
Three solutions?!
No. Though it has 3 solutions in normal Nurikabe, it has only 1 solution in Nurikabe II which is much stricter.
And now for something completely different … in your Logo I can identify Yajilin, Sudoku, Nurikabe, Numberlink and Akari. But what is the last one?
The last one is Tapa. Not from nikoli, but I can’t think anything else when I made the header.
Ah, this should be a “1/1” clue in R2C1 🙂
BTW: I love Tapa!
