I'm 2h 18m into a run and this is where I'm at. Here's the key:
- Navy indicates boxes I can opt into without having to progress some unknown distance into the game.
- Brown indicates things whose locations I know but haven't yet obtained.
- Yellow indicates squares I have achieved.
- Red indicates squares I can't achieve.
My best bet for hitting bingo at this point is the TLBR, ROW2, COL4, or ROW5. I've got about 9k sen stored up, so ROW4 and COL3 are also possibilities. At this point, the real question is just which of the bingo items I find first!
