Can I make my own geocache based upon Geodyssey?

Sure. The easiest way (but certainly not the only way) is to create a puzzle cache that requires the solver to complete the Remote Challenge. On the Remote Challenge Final Page is a 1,024-character one-time pad (randomly generated using random.org) that can be used to encrypt your own message that leads your solvers to your cache. See my Geodyssey geocache (GC5CJ31) for an example. FYI: Rumkin has an excellent free tool for encrypting and decrypting messages with one-time pads.

Can I make my own puzzle based upon Geodyssey?

Sure, as long as you follow the terms of the license. You don’t need my permission as long as you (a) give me credit, (b) don’t make money off of it, and (c) distribute your work under the same license terms. If you want to create and distribute a derivative work under any other terms, please contact me – I’m not opposed to making a deal.

Did I solve the puzzle or complete the challenge correctly?

If you found the link and password you needed to move on, you solved the puzzle correctly. If you entered the correct password on the Final Page of the challenge, then you completed the challenge correctly.

Did you finish it like I originally intended when I constructed it? Probably, but not necessarily. Several solvers have found alternate solutions to some of the puzzles that led them to the correct passwords, links, or locations.

If you feel you missed something and want to experience all that Geodyssey has to offer, let me know.

What does the name “Geodyssey” mean?

First, it is a portmanteau of the prefix geo- meaning “of or relating to the earth” and the title of the classic Greek play The Odyssey, which tells the tale of the travels of its main character Odysseyus.

Second, it is a play on the word geodesy, which is the scientific discipline that deals with the measurement and representation of the Earth.
