Wachtwoord vergeten?

 

In 2023, WCPN celebrates its 10th anniversary! We would like to celebrate this milestone with a puzzle competition for our members. During the winter holidays (December 22 to 31), WCPN and ORTEC are organizing an online puzzle competition in honor of our 10-year anniversary. Enjoy a week of beautiful logic puzzles and sudokus.

Extended puzzle bliss: Puzzles and Sudokus mixed together

For our anniversary, we're hosting an extra-long competition lasting 4 hours, featuring a mix of puzzles and sudokus. During the winter holidays (December 22 to 31) of 2023, you can participate in this online competition. More information about the competition is available on the instructions page of the anniversary competition.

Who can join?

Anyone can join the anniversary competition! The competition consists of different levels of puzzles and sudokus – 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!

How can you join?

The registration process for the anniversary competition is easy: Fill out the registration form. Once you're registered, you can participate in the anniversary competition. More information on how the anniversary competition is organized can be found on the instructions page of the anniversary competition.

What puzzles and sudokus can you expect?

The anniversary competition will feature a wide variety of sudoku types and logical puzzles. Examples of these can be found on the championship pages of previous years. No instruction booklet will be published for this competition, so the exact types will remain a surprise until the last moment.

Also, check out this cool booklet that ORTEC and WCPN created in 2019. It contains many of the puzzle types you can expect in the championships; an interview with previous Dutch Champions Annick Weyzig and Karin Griffioen; and maybe most importantly: it contains tips from Annick and Karin that may help you improve your solving skills.

What is at stake?

There's one thing that's yours to keep forever: eternal glory! Beyond that, in this anniversary competition, there's nothing at stake; it's all about having fun and, of course, earning that eternal glory!
