    I’ve always been bad at snake puzzles but the last couple weeks have forced me to get better. This one was the sort of solve where I go from “I have no idea how to even start this” to a slow but steady flow of ahas, which I always particularly enjoy.

    Snake variants are one of my worst puzzle types. I can never figure out if they’re supposed to be primarily deductive, like most object placement puzzles, or more intuitive like a Numberlink

    • Jack Bross says:

      As far as I can tell, the answer to “deductive or intuitive” is basically just “yes”. I tend to make enough logical deductions to get some basic constraints and a vague idea of how it has to go, then hack together an approximate solutions, then tweak. At least for harder puzzles — the easy ones you can just sort of logically follow your nose with a little bit of “make it look like a snake solution” intuition.

      In the case of this puzzle, the rough structure can be figured out pretty logically, but I had to tweak to get the balance of the halves down.
