The reason, I waited until after posting all 3 of the puzzles was that once you know where the site was, you would probably have found the puzzles and their solutions.
The puzzles were found as videos on the Scam School YouTube channel with Brian Brushwood. So below are the videos.
UNBEATABLE Number Puzzles (direct link)
The HARDEST Puzzle Yet! (direct link)
The HARDEST Puzzle… Part 2! (direct link)
Note that there are other solutions possible to some of the puzzles, these are not the only solutions.
PS: As a non-drinker I don’t really condone the use of these puzzles to get frinks (free drinks).
