It's not based on the presence or absence of certain symbols, because 0 and 1 are koans but 01 is not.
It's not based on counting anything, because 10 is a koan but 01 is not.
The only single-digit nonkoans are 3 and d.

Is there a reason you skipped 07 through 90?

Yes: 22
No: 0a, 0b, 0c, 33, 44, 55, a0, b0, c0

The reason is that I only get so many guesses and I wanted to diversify a bit.

I am putting this round on hiatus until my laptop recovers from its disagreement with my water glass. I am attempting to give it emergency medical attention now. It will probably be fine, but I would prefer not to run the rest of this game from my phone.

Anybody else want to go in the meantime?

Edit: it might be simpler of somebody else starts a game from the other thread.

And apparently my computer is smarter than I thought. The only hardware problem I know about is that the builtin keyboard keeps spamming keys I don’t want to type. My computer is apparently smart enough to say “That keyboard doesn’t work; I will ignore it” once the real OS boots; it’s only the boot menu and the self test which care about the constant flood of yyyyyyyyyyyyyyyyyyyyyy.

All no, ff is repeated.

You dropped the initial post URL again.

(Also I have no idea what hypotheses fit this data and am probably not up for guessing anything useful right now. :P)

Hint: Y’know, there’s a reason I gave you a longer yes string (0x98521, listed that way because spoiler plus code doesn’t work).
