My parents and I have been solving puzzles together for many, many years. This upcoming Monday is my father's birthday, and I plan on compiling some of the puzzles that I've contributed here into a small "magazine" for my parents to solve in their free time.
I would love to use some puzzles from other members of the site, but I feel crummy using them without permission, so I'm asking here -- If you have any puzzles you particularly like and would not mind being used in this gift, please post links to them in an answer below! Hopefully I can load up a bunch of awesome puzzles and make a really cool little gift.
My parents (and I, not shockingly) prefer word puzzles and riddles over other puzzles, but things that are solvable without a computer, such as math puzzles, are okay as well. I'd like to avoid any sort of cryptography puzzles because I want a list of puzzles that are solvable from any location. Technically, a lot of the ciphers can be solved from other locations, but I'm not going to ask my parents to figure out a Vigenere on the fly.
There are a few specific puzzles/users that I'm going to target as things I'd like to include, but for now I'm opening up the floor to see who wants to volunteer their best work.
Thanks ahead of time!
P.S. I have no idea if this is the right place for this, or how to tag it. If this can't/shouldn't be here, let me know.
