What is Aachen Open 2011?

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.

In 2009, students from RWTH Aachen University successfully organized Aachens first speedcubing competition: Aachen Open 2009. The event was a big success which pushed the capacities of the venue to its limits because of the high number of participants and guests.

In 2010, we were able to follow up on the success of 2009 and even exceed it with Aachen Open 2010, which was at that point the biggest german speedcubing championship (except from World Championships 2009).

Third time is a charm, so we decided to try to beat our records again in 2011 and get even more people to compete. We are confident that we will succeed and that our event will be as nice as before. You are welcome to join us!

Where and when?

January 14th/15th/16th, 2011

Computer Science Building, RWTH Aachen University
Ahornstraße 55, 52074 Aachen

How much does it cost?

The entrance fee for saturday and sunday will probably 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! Friday will be free (no drinks or food included).

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!
