See regular Heyawake rules.
Rules for this : The numbers show the different blocks of connected unshaded groups within the region. The numbers are all wrong. The number of numbers that there should be are also wrong. e.g. a 14-18 clue means there won’t be any unshaded group of 14 cells, or of 18 cells, and there cannot be exactly 2 groups of unshaded cells in that region.
Rated : Hard due to unfamiliarity, and general confusion.
