The World Puzzle Championship (WPC), first organized in 1992 in New York City by Will Shortz, is an annual competition featuring language- and culture-neutral puzzles, primarily puzzles involving logic and reasoning, to allow puzzlers from around the globe to compete on equal footing. The three day event features hundreds of puzzles, organized into both individual and team rounds, to challenge the world’s best puzzle solvers. Hosts come from the different member nations of the World Puzzle Federation.
In 2006, the World Sudoku Championship (WSC) became a second annual competition organized with the World Puzzle Federation, focused on Sudoku puzzles and their common variations with a similar competition structure to the WPC. Currently, the two events are held together in a puzzle-packed week with two days for the WSC, a break/excursion day, and then three days for the WPC. Hungary was already the host in 1999, 2005 and 2011.

Anyone with an interest in solving sudoku and/or logic puzzles for several days straight is welcome to attend one or both of the championships. The main thing to note is that, following the Olympics tradition, there is a maximum for how many competitors each country can have on their “official” team which is 4 competitors for the WSC and 4 competitors for the WPC. What does this mean:
– Individual member nations in the World Puzzle Federation are  listed here.
– If you live in a member nation and want to compete on an official “A team”, you need to qualify through your country’s qualification process. Contact your country’s representative for more info.
– If you live in a member nation and won’t be competing on an “A team”, you are still welcome to attend. Notify your country’s representative about your wish to attend, and you can be added as an unofficial competitor or guest.
– If you do not live in a member nation, you can register directly as an individual using the Registration page. Please also apply for WPF personal membership if you are not already a member. You will be an “official” individual competitor, and can join up as part of a UN team with other unaffiliated solvers to experience the team competition as well.
– If you’re not sure about the status of your country or WPF membership, please contact the WPF office@worldpuzzle.org

The venue for the WSPC is the Hotel Eger&Park, in north-east side of Hungary.
The hotel is located 5-10 minutes walking distance from the heart of the city.
The town of Eger is 1,5 hours from the Budapest Ferenc Liszt International Airport.

As part of registration, the organizers will provide transfer to and from the airport
if your travel happens on official arrival and departure days (September 21, 23, 25, 28, 30). On other days, additional fees apply.

If you need visa, we can provide you an invitation letter in order to help your visa application. Please, check your country’s status on the website of the Ministry of Foreign Affairs, where you can also download the Visa Application Forms if it is needed.

Basically, no. To provide the best rates for the event including the competition space we have made some minimum reservations with the hotel including room and food.
As soon as we reach those minimum numbers, registration will be allowed without staying in the hotel.
