theCODEBREAKERS - 2020 edition

Get to know secrets of cryptology, break ciphers and win against players from all over the world

theCODEBREAKERS
Acquire knowledge

Cipher course

The main theme of the game is a cipher course. Each player takes on the role of a cryptology adept who learns increasingly difficult, historical ciphers during the game. The participants use their acquired knowledge in practice, by solving cryptological tasks, to compete with players from around the world. Competition, time pressure, challenge and mystery - these are four inseparable elements of a cryptologist's work.

Cipher course

Three levels of difficulty

TRIAL
REGISTER EVEN 1-PERSON
TEAM AND TRY THE GAME

is a one-person game that during six lectures will allow you to learn the basics of a cryptologist's work, encompassing simple codes (including unbreakable ones!) and will enable you to face the first cryptological challenges.

BASIC
1-ST CHALLENGE: 26.10
DECISIVE STAGE: 13.11

This is a meeting with historical methods of hiding information, which are the basis of education of every cryptologist. They must also be known to future Enigma Busters at the beginning of the Cipher Course, which made them cryptologists. At this level, 3-person teams will play in cryptology adepts.

ADVENTURE
1-ST CHALLENGE: 09.11
DECISIVE STAGE: 27.11

is the next step in exploring the cryptology craft. A real adventure with ciphers, including the famous "le chiffre indéchiffrable". As it turns out, this "unbreakable code" will sooner or later be attacked by your team. All you need is a bit of cryptological intuition...

Are you afraid that you will not handle it? Take it easy, with the help of our code breaking tools and the hints of Enigma, you will surely be able to handle even the most difficult tasks.
Compete

Players from all over the world

Compete with players from all over the world, decode secret messages first and win crypto prizes. In the previous edition, over a thousand crypto-enthusiasts from all around the world participated in our game.

In 1929, three math students began their adventure with cryptology.

Enigma

It resulted in breaking the secret of the German encryption machine Enigma.

Commemoration

Our mission is to spread the memory of the success of Polish mathematicians, the conquerors of the Enigma cipher. This event had a significant impact on the fate of World War II and changed cryptology forever.

Unbreakable cipher
They did the impossible

Unbreakable cipher

The Enigma was a military encryption machine used by the German army from 1926 until the end of World War II. The machine generated unimaginable combinations and for a long time its cipher was considered unbreakable.

They faced it

Machine cipher

Learn the history of the encryption machine guarding the military secrets of the Weimar Republic and the Third Reich, which for many years was a challenge for the secret services of many countries.

How did they do it?

Busters of the Enigma cipher

Polish cryptologists initiated a major revolution in cryptology. They launched thire attack on the code from a new mathematical perspective, rather than linguistic. Marian Rejewski discovered the cyclical nature of the Enigma cipher and then developed a mathematical model of a machine that he had never seen before and he never would see it! It was the key to the further success of the Polish team.
