Heyawake Dynasty-style: Shade some cells black so that no two black cells are orthogonally adjacent and all white cells are connected. A number inside a black bordered region—a room—indicates the number of black cells in the room. A run of contiguous white cells in the same row/column cannot span over two room boundaries.

Puzzle 82: 5×10
Heyawake
Second rejected puzzle. As you can guess, some of the top rows would have become the answer keys, and the bottom part I still can’t figure out a logical solution for.
Three more to come. Also the ordering of how these puzzles appear is determined indirectly by Yoshiap, whose I simply asked “give a permutation of 1,2,3,4,5”. 😛
