Solving Guides!

Looking for solving guides for Ciphers? We have many excellent guides written by ACA members that should put you on the road to solving ciphers faster.

Cipher usage for Division B/C this year.

If you are trying to figure out what ciphers will be used for what type of event, we have a nice Summary of Ciphers used for the 2023-2024 Season that was made by reading the current rules. As always, any official clarifications or rule updates override anything on that page, but it is a good start.

If you are looking for a resource sheet to print out for practice, you can find it here.
