Here is a link to a GitHub gist containing a link to the Penpa+ port of this puzzle; the link is so long that not only can I not paste it here, but TinyURL refuses to load it. For anyone who comes across this post in the future and wants to attempt this behemoth, I hope you find this useful. https://gist.github.com/edderiofer/0c3775d1ed838950d3852932d2d53764

Good luck.

]]>For Kakuro with Pentominoes, first of all I think you can get virtually everything in the top right and bottom left once you get the magic number. (EDIT: Or rather, there are a few pairs that are resolved later. This is probably why you said “few” instead of “all”. You probably did get as far as you could in these corners.)

After that, think about the top left square where the 9 and 20 cross. If that cell merges with the cells below to make a pentomino containing all the numbers of the 9 sum, then the other two pentomino cells are 8,9, contradicting the vertical 6 sum nearby. This is enough to deduce that it’s an L pentomino containing all numbers of that 20 up top. Now you can get a whole bunch of other pentominoes, and this opens the door for a lot of “sum this group of cells in two ways” logic.

Intersections: Personally I thought this puzzle (and this type) was pretty silly since it makes literally no use of the grid. You didn’t even need to write the numbers into the grid to get the answer.

Kakuro: It was nice, somehow I got stuck on this for a while.

Nurikabe Loop: Liked the interactions between the loop and the islands in this puzzle.

Outcast: Glad I skipped it on the test, definitely the longest puzzle in terms of time. I thought I broke it a few times only to realize that I missed a word in the word bank.

Kakuro with Pentominoes: Can I have a hint on this puzzle? The only progress I’ve made is a few numbers in the corners + middle row and that the sum is twenty-six.

Anyway, I’m hoping for 240 + 2 differences assuming no answer entry mistakes.
