Cryptoleague is now non-functional due to new data protection laws that I have not had the time to implement.   Existing users have been deleted from the database.

On CryptoLeague.com you have the opportunity to test the twistyness of your thinking.   We offer Cryptographic puzzles ranging from simple substitution ciphers to complex polyalphabetic ciphers.   These puzzles are not intended to be the simple encrypted quotes that some people can solve in seconds with a bit of inspired guessing - they are much harder than that.   With the help of our sophisticated solution front end you can call on a number of tools to assist you in this process.   For example, statistical analysis can reveal much about the prevalence of individual letters.   For more information on our puzzles, please select the puzzle menu option from the menu to the left.

Registered users can also submit their solved puzzles to the website where the results are used to build league tables of user performance.   Time to solve and any hints or tools used are also recorded in the tables.
