Happy 1000th! Go Brian!!!#5: Valerie Mates (valerie) on Nov 21, 2022 [HINT]
To solve it, I used internal edge logic on the 6 in column 2, and then a lot of careful color logic.#6: Andrew Schultz (blurglecruncheon) on Dec 31, 2023 [HINT] [SPOILER]
A great way to celebrate the milestone. The angled perspective is a cool way to make a non-trivial solve.
I enjoyed the color logic dance at the end.
To be super specific (since I replayed this, it was neat enough,) C2 R16-20 R1-3 are knocked out by internal edge logic (otherwise a 4, or 2 black islands, in C3) and C3R15-13 can't be both black and red.
C3R7 C4R8 C5R9 C6R10 are the only reds in their column, then C7 only has 2 places for its red 1. Another diagonal of reds starts at C7R1.
Now off to see if you made one for 2k ... I can't remember!
