The contest runs from October 21st to end of November 2019.

This game mixes short lectures about the secrets of the ENIGMA cipher machine with interesting challenges.

Registration is open already under "THE CODEBREAKERS".

The challenges are presented in 3 levels (Trial, Basic and Adventure). For the Basic and Adventure levels, teams are invited to participate; for the Trial level also single persons can participate. So this is for beginners as well as for experts.

To win, the time that you need for the final task is the most important thing. If needed, notes, time bonuses, and "cryptologic bombs" are available to help to solve the tasks.
