@emmettcito: That's an elegant way to do it! I hope it works out :-)

@SudokuExplorer I was thinking to have normal numbered killer cages but only the cells in the shaded loops count towards the cage totals.

@Phistomefel: I'm really pleased you're enjoying the logic! A Nori^3 killer sudoku is something I've been thinking of setting in the future, though I'm still exploring break-in logic ideas. One possible way could be to have adjacent coloured cells have opposite parity (even/odd or high/low). If that doesn't work, another way could be to use minesweeper clues.
@emmettcito: I hope you succeed in setting one! It will be fun to try one :-)

@Phistomefel that is a fantastic idea! I might try to construct something like that myself!

Thank you for your new invention of Norinorinori. I really enjoyed discovering the new logic in there. Out of curiosity: are you planning to construct a Norinorinori Killer? I'd be looking forward to it. :)
