Surveyors Heyawake Shade some of the cells black. No two black cells may be orthogonally adjacent, and all white cells must form a single polyomino. No continuous line of white cells may span over two room borders. In addition, the following rules govern clues:
For clues inside the grid, each clue can tell either the number of black squares in the region it’s contained in, or the number of black squares adjacent to it (including the cell itself). It might be both.
For clues outside the grid, each clue can tell either the number of black squares in the row/column, or the length of some maximum continuous line of white cells (it cannot be extended, as in it is obstructed by either the grid’s edge or a black square; note that “maximum” doesn’t refer to the maximum length, but rather the nature of the line). It might be both.
Answer key: Enter the lengths of the lines of white cells in the marked row/column. If the row/column has all white cells, enter 0.

Sixth preview puzzle. Do you note that each of 2,3,4,5 appears exactly once in the grid and exactly once outside the grid? That was a theme, but a minor one. The major one is the obvious “wiggly” rooms everywhere, which is a pain to make with MS Excel.
