But man, even these low-reward puzzles are impossible to crack. Either there’s no explanation, it’s straight-up wrong, or it’s just unsolvable.

Interesting code. I feel like all these puzzles goin’ around are unsolvable. Especially if nobody’s cracked it in seven whole years. That’s wack.

We all know very well that every puzzle can be solved, and it's only due to the vastness of their scope that we end up saying they’re unsolvable! In my opinion, linear search is pointless and only the search steps themselves should be considered. Although in this forum, no one fully shares their methods, according to a previous user, they claimed to have completely searched the 60-bit space. However, it seems they’re not being honest and may not have searched at all. I hope to solve puzzle 71 soon, and if the user had asked for help, I will assist them when I do.
