In my opinion, these puzzles were all manually created by their designer and are not derived from a deterministic wallet. This is because there are no visible patterns in these addresses that are typically found in deterministic wallets.
Bold part by me. I'm genuinely curious what kind of patterns you think are visible in deterministic Bitcoin wallet's addresses. Seriously, enlighten us!

Care to show some examples? Though, maybe rather not, because there are almost certainly none and we already had to endure a lot of crap here.
