It is once again time for Konglig Datasektionen’s yearly puzzle hunt/CTF competition dJulkalendern! Do you have too much time to study? Exams to procrastinate? Homeworks to ignore? Wonderful! Come and compete for the title Bäst på att DATA™!

A challenge is released every weekday in December until Christmas Eve at 12:15 CET and your task is to solve it as fast as possible! The challenges are cryptic puzzles, hacking and other computer science related things! The calendar also has an intriguing story that unfolds as you solve each window.

The competition is individual, but cooperation is encouraged if you get stuck!

The winner receives the title Bäst på att DATA™. There is also an achievement patch for those who solve all windows and those who do it the quickest will receive dJulkalendern-themed T-shirts!

You can already go to https://djul.datasektionen.se and solve the introductory window, -1, make sure you understand the system and read the rules!

You should also join our discord server: https://djul.se/discord, where you can ask us questions, discuss the windows you have solved and be notified about any possible hints!
