Is there a directory of Crypto puzzles created until this day?

[l3pox]

Hey dear friends, since I heard from Coin_artist crypto puzzle: 1flame I got really intersted on Crypto puzzles and its solutions.

I've been organizing some of the published solutions on this spreadsheet:

but is there any kind of history/directory of known crypto public puzzles to learn more about its history?

looking forward for any insight on the subject.
thanks.

(MOD: please, move it to the appropriate forum if here is not the best place, thanks)
