# Puzzle 191: Heyawake

Here’s another Heyawake. It was inspired by a deduction that I found while solving a puzzle due to @Nana_sleep, though that wasn’t actually necessary. (Viewing that link might serve as a bit of a spoiler to this one.)

# Puzzle 162: Starwacky

This one is a hybrid of Starbattle and Heyawake (Heyawacky). Since apparently I haven’t had enough skyscrapers, I keep misnaming this “Skywacky”. Inspiration?

Rules Solve as a regular Star Battle. In addition, connected stretches of empty cells aren’t allowed to cross more than one region border.

# Puzzle 68: Summawake

Here’s a practice puzzle I made for the German puzzle championships, which took place end of June. The puzzle is a Summawake, a variant of Heyawake that I haven’t seen before. I believed the competition puzzle (and the type) was due to Florian Kirch. It’s actually due to Ulrich Voigt! The instruction booklet has an example. Rules Shade some cells, such that all unshaded cells are connected by edge, and that no two shaded cells share an edge. A horizontal or vertical stretch of unshaded cells may cross at most one area boundary. In addition, if there are any unshaded clues within an area, the number of shaded cells within that area must be equal to the sum of unshaded clues within that area.
