Recently I worked my way through Selected Puzlova, a puzzle book that was being sold by the Japanese team at WSPC 2023 in Toronto. It is an English compilation of some of the best puzzles from the Japan Puzzle Federation's magazine Puzlova vol. 1-7, and can be found online here: https://jpf.booth.pm/items/5288768. A very fun book with many wonderful puzzles, well worth spending all those hours on. But of course, way more importantly, I also found a couple of genres that don't show up very often and which I would like to try writing a GAPP in. Here is one of them!

Today's puzzle is a Pentomino Room!

Rules: Shade one pentomino (a contiguous region of five cells) in each outlined 3x3 area, such that every pentomino from the shape bank given outside the grid is used exactly once. Rotating and reflecting shapes is allowed. An equality (=) sign indicates the two cells adjacent to it are either both shaded or both unshaded. An inequality sign (≠) indicates that of the two cells adjacent to it, exactly one is shaded. Cells containing a cross mark cannot be shaded.

Acquire a Speedy Sloth 🦥 by solving the puzzle in 2:30 or less!
Obtain a Quick Crab 🦀 by solving the puzzle in 5:00 or less!
And all solvers who complete the puzzle will be rewarded with a Puzlova Palila 🐦!
