I made a set of puzzles last year for the World Puzzle Championship held in Kraków, Poland. It was part of a round of new genres, with puzzles by the inventors of those genres. So hot off the heels of coming up with La Paz, that was what they wanted me to make! I had to wait until this year to post due to contractual obligation. Shade some cells so that no two shaded cells are orthogonally adjacent and divide the remaining unshaded cells into two-cell regions. Clued cells cannot be shaded. A clue indicates the number of shaded cells which lie entirely within the same row or column as the region containing the clue Puzzle 1 Solve on Puzz.Link
Puzzle 2 Solve on Puzz.Link
Puzzle 3 Solve on Puzz.Link
Puzzle 4 Solve on Puzz.Link
Puzzle 5 Solve on Puzz.Link
Fantastic progression, #4 & #5 were very satisfying
