Like most social events, puzzle hunts are much better in person. That said, the creators of this year's Mystery Hunt really delivered, creating a hunt that was as good as it could have been under the circumstances.
In September I published a puzzle called Losers and Winners. At least five people solved the puzzle (unlike my first puzzle, which no one solved without hints). Here are a few hints, in white text, meant to be read in order.
