    A great puzzle, Grant! I finally solved it on my third try. The funny thing was that both times when I restarted thinking I had broken the puzzle, I actually hadn’t made any mistakes, (but instead was just missing a possible factorization preventing me from making progress).

  • Great puzzle! Seems like there couldn’t possibly be enough information with no operations and all those unclued regions, and then suddenly the possibilities fit together and it all solves smoothly. Wonderful fun.

    Does the intended solution involve noticing R1C2 and R7C2 are both 2/4 in two cases? That’s quite some lookahead, especially with things like this that need remembering the possibilities while doing intensive logic (in this case math). It’s an excellent puzzle nonetheless.
