What is Aachen Summer Open 2012?

Aachen Open is the biggest annual german tournament in speedcubing, the sport of solving Rubik's cubes and similar puzzles as fast as you can.

Where and when?

Lecture Hall Aula II
Computer Science Building, RWTH Aachen University
Ahornstraße 55, 52074 Aachen

How much does it cost?

The entrance fee for saturday and sunday will be 5 euro per person per day. This applies to everyone (except reporters), no matter if you are a competitor, guest, parent of a competitor or someone else!

Where can I sleep?

There are plenty of hotels in Aachen, check for example and look for hotels in "Aachen Zentrum.

Aaaah, I never attended a competition and I feel totally lost!

Don't panic! Everybody is welcome and it's not about winning. You will most likely not be the only one who needs more than a minute to solve the cube.

There will be plenty of time to test the equipment (for example the official timing device, the Stackmat timer) and discuss the rules, if you have questions. However, every competitor should have read the official WCA regulations at least once before attending a competition. You should also have a look at this very nice competitor tutorial.

I have questions, which are not answered by this website!
