You are viewing a page in the memory competitions section. To update or add a competition, please contact us.

From the announcement:


Venue: Bielefeld, Germany

Date: 23-25 September 2016


Calculators will have to solve tasks in different categories (addition, multiplication, extracting roots, day-of-the-week calculations) and various surprise tasks. Only strict mental calculation (no tools, no writing down of intermediate results) is allowed.


There will be several titles and trophies for the best participants. In particular, the MEMORIAD Association will sponsor free flights to the MEMORIAD 2016 competition (planned to be held in Las Vegas, USA) (http://www.memoriad.com) for the winners in the categories addition, multiplication, square roots and calendar calculation as well for the winner of the combination (does not apply for participants who are not allowed to enter MEMORIAD contests according to decisions of the MEMORIAD Association and for calculators who have already won a free trip to Memoriad 2016 at MCWC 2014).


The registration form can be found on the MCWC web site;


Calculators who already took part at a previous MCWC event are welcome to send the application form by e-mail to [email protected] . First-time participants please download the entry form on the MCWC web site. Please send it by airmail together with the documentation that is necessary for qualification to the address given in the form. Please note that we have a tough qualification (in 2014, 40 calculators out of 74 who have registered were qualified). Calculators who took part in one of the previous years may want to send additional documentation about their recent results in the same way as the first-timers (by airmail with all the paperwork) in order to have better chances in the qualification.

Deadline for Registrations: 1 June 2016 You can help us with the organization if you register soon.


The number of participants is limited to 40. If more people register for the event, the organizer will select the participants who qualify. For this purpose, information about previous results at mental calculation events (achieved in the past ten years), other mental sports contests and verified achievements with the Memoriad software (http://memoriad.com/memoriadsoftware.asp) are taken into consideration. The results achieved should be documented (category, number of correct answers, time) and sent together with the application form. These results must be confirmed by a witness with some background in mental calculation (for example a math teachers or a university researcher who works in a field close to mathematics).


Participants have to pay their travel expenses and their room at the youth hostel. We have a reserved a number of rooms until 29 July. Use the keyword "WM 2016" when booking! If necessary, we will try to support those who need a travel grant by looking for sponsorship. Please contact us as soon as possible if you are in need of such a sponsorship. And of course, it would also be very welcome if you or your company would offer sponsorship!

Please contact us soon enough if you need a formal invitation letter for visa purposes. Keep in mind that in some countries visa formalities can take a long time!
