This challenge originally launched in December 2020. The deadline for winning prizes is over now, but the challenge itself with all the puzzles remains online, so feel free to take up the challenge at any time.
We have created a github repository for sharing, discussing and comparing puzzle solutions.
WARNING: this repository contains spoilers. Better visit this repo after you have tried the challenge yourself.
The following rules only apply for those who finished within the deadline.
The rules are easy... Have fun and don't lower the fun of other people.
The challenge starts on December 2nd and will end on December 31st, 2020.
Getting to the end of the challenge is enough to be in the lottery, but solving more puzzles will increase your chances
of winning one of the ten prizes. The prizes consist of awesome things like an XBox Series S, a 3D printer, dev kits and many more.
For your convenience, you can create a user account to save your progress. Of course, you can also
participate without registering and use your good old fashioned writing pad.
But to receive your prize, you will have to give us at least a working e-mail address - which can also be
temporary.
You can also participate as a team - team players are very much welcome here. In that case, please create one account for the whole team.
Our terms and conditions apply.
We are excited to hear from you. For this, you can use our e-mail or our social media channels:
The absolutely most awesome challenge ever.
Not enough cats... I was hoping to see more cute cats but was not happy. I would not recommend.
Captivating and exciting!
