(For those who are interested. I'm a bit behind, but I don't think anyone else on Maxim's list has finished, either.)
Day 23 (Crab Cups) required some cleverness. The first puzzle is solved with a simple solution, and the second puzzle is easily generalized from it... but will take a LONG time (hours certainly, days possibly) unless you rethink the data structure.
Looking at others' solutions, it seems that Gautier, Maxim, and I have similar approaches, but all of us use slightly different data structures.

Correction: Gautier de Montmollin finished, and I somehow missed that.
For what it's worth, Day 24 is actually straightforward, so long as you can figure out a hexagonal map. Maxim Reznik's solution avoids the guess-and-check I applied to determine the playing field's size (which was not given, interesting enough).
