Edit: it's definitely the wrong one, from poking around the site out of confusion it turns out you have to be logged in to access previous days' puzzles - but the game page itself does absolutely nothing to tell you this and just loads today's puzzle if you open an archive link.
I don't exactly feel like handing over my phone number just to play a puzzle game. Bummer, I guess.

Fun little logic puzzles for sure. Nice job!
edit: HN stripped the emoji but I did solve it, lol
