Used to love logic problems like this when I was a teenager, I’d go through books & books of them. Clearly getting older has made my brain rusty, as it took me three attempts, but got there in the end.

I spent a long time solving it, just to be 44 minutes late. Does anyone know if the puzzles always expire at 00:00 UTC Thursday and Monday? There should be timer on the puzzle pages, ideally.
The official rules have the exact timeframe for each puzzle. And yes, it’s always midnight UTC that each one begins/ends, the number of days varies.
