We are happy to announce the Dutch Puzzle and Sudoku Championships 2026! In the weekend of Friday March 6 2026 to Tuesday March 10 2026 , WCPN and ORTEC organize online qualifications for the championships that will take place on Saturday April 18 2026. Enjoy beautiful logic puzzles and sudokus this weekend.

Two championships: Puzzle and Sudoku

As always, there are two separate championships: one for sudoku and one for logic puzzles. This year, the championships consist of two parts. In the weekend of Friday March 6 2026 12:00 pm CET to Tuesday March 10 2026 11:59 pm CET the online qualifications for both championships will take place. More information about the online qualifications will follow soon. The live championships will be held on Saturday April 18 2026 at ORTEC headquarters in Zoetermeer.

Who can participate?

Anyone can join the online qualifications! The championship always consists of different levels of puzzles – so whether you consider yourself a beginner or an expert, there will surely be some puzzles for you. And the cracks can of course try to solve them all!

As always, there are two separate championships, one for sudoku and one for logic puzzles. Most participants will compete in both championships, but prizes will be awarded separately for puzzle and sudoku. You are not required to join both qualifications. But because only a limited number of participants can qualify for either championship, you increase your chances if you participate in both qualifications.

There are three participants categories: participants from WCPN, participants from our sponsor ORTEC and other interested people. After the online qualifications, the best WCPN and ORTEC participants will be invited to participate in the live championships. More information on the distribution of invites between these 2 categories and the 2 championships will follow after the qualifications have taken place. During the live championships, a champion from each category will be announced. The best participant from the WCPN will be crowned Dutch Champion! So, if you want to be eligible to win the title of Dutch Champion, make sure you join WCPN.

How can you participate?

The registration process for the championship is simple: fill out the registration form. Once you are registered, you can join the online qualifications. More information on how the qualifications are organized can be found on the page with instructions for the qualifications.

What puzzles and sudokus can you expect?

The Sudoku Championship will contain a wide variety of sudokus, and the Puzzle Championship will contain many types of logic puzzles. You can find examples on the championship pages of previous years. Furthermore, 2 weeks prior to the qualifications an instruction booklet will be published that contains more information on the exact types of puzzles that will be in the championships.

Also, check out this cool booklet that ORTEC and WCPN made. It contains many of the puzzle types that you can expect at the championships; an interview with multiple Dutch Champions Annick Weyzig and Karin Griffioen; and maybe most important: it contains tips from Annick and Karin that may help you improve your solving.

What is at stake?

There is one thing that nobody will ever take away from you: eternal fame! There are multiple chances for eternal fame: there are separate competitions for logical puzzles and for sudokus.

Next to eternal fame, the top finishers will also be eligible for a place in the Dutch national team representing The Netherlands at the World(!) Puzzle and Sudoku Championships. The World Puzzle and Sudoku Championships 2026 will take place between October 11th and 18th in Kolkata, India. For participation in the World Championships, you have to be a WCPN member and have the Dutch nationality.
