A puzzle for which if there is a hate button ,I would be more than willing to press it.Despite progressing in the right path,the top right corner made me think that I was solving wrongly because I simply couldn’t find a way to put that F and make it work until I just like that stumbled upon the right way of fixing that corner.
More than 2 hrs to solve this nasty puzzle.
Grant, I thoroughly enjoyed this pair of Pentominous puzzles. Fun starts from the corners and then some surprisingly large open spaces leftover that still yield unique solutions.
I find myself wanting to solve, (or compose), some more Pentominous puzzles now. So, thanks for the inspiration!
Skynet, yes, the F took a fair bit of analysis. What helped me to make that analysis manageable was not to fully place an F pentomino, but just consider where the 3-in-a-row portion of the F might be placed. Approaching it like that made that step feel quite fair to me.
