I was playing with a few different notation styles (lines, shading, letters, …) through the week on Penpa, and admit this is one of the puzzles where multiple defaults (and even multiple solution checking options) may be best. Please share your comments on how you prefer to solve Pentominous puzzles and if you could make this work in Penpa. We will probably document all of these methods when we formalize the user experience for this style and for Fillomino.
This upcoming week will feature Statue Park puzzles and will also include a large variation as a Sunday Stumper.
