Yes, you did in fact read that right- this post contains 12 puzzles. I had an idea for a pentomino themed set and yesterday, decided to see if I could get the entire pack together that day. I managed to construct all 12 puzzles and left the testing for today, fixed a few errors I had made, and here it is. I'm extremely proud of this set even without the fact that I put it together in a day.
This post won't have preview images or rules for each puzzle, but I will link them all here. The pack has a penpa link with answer check and rules written in alongside an image, so the pack can be solved physically or digitally without issue. The U puzzle has the variant of unequal lengths.
puzz.links for
P,
W and
X can also be used. There was no way to make one for Z, unfortunately. Comments after the break.
