X International Origami Internet Olympiad

Published 01 oct 2025 at 23:55

The 10th International Origami Internet-Olympiad will be held online from November 15th, 2025 to December 15th, 2025 (The exact time will be specified in the contestants′ control panel!).

Participation is free. Every registered origamist has the opportunity to take part in the Olympiad.

How to participate in the Olympiad:

You need to register at origami.expert
All participants must fill out the FOLDER APPLICATION FORM.
The application must be submitted no later than November 15th, 2025
(the exact time and other useful information can be found on the Official IOIO-2025 page).
After the start, you can find the tasks in your profile.
The Olympiad e-books are FOR PERSONAL USE ONLY and may not be distributed online
(or published in any other way).
The Olympiad consists of approximately 10-12 tasks: diagrams of various difficulty levels (from easy to complex), CPs, tessellations, etc., and a theme for your own work. Each model will be awarded a certain number of points. Photos of completed tasks must be submitted no later than the exact time specified in the contestants′ control panel!
The winners will be selected by a competent jury within three weeks after the deadline.

For Designers: If you wish to participate in this event, please fill out the special APPLICATION FORM with your diagrams, CPs, or photo-diagrams by November 1st, 2025. If your diagram is selected for the Olympiad, it will be added to the e-book with tasks. All authors who submit their diagrams will receive the Olympiad e-book via email. The quality of the diagrams, CPs, and photo-diagrams doesn′t matter, as all diagrams will be tested and redrawn in the same style. This is a great opportunity for you not only to obtain high-quality tested diagrams of your models but also to see them folded by many great origamists worldwide.

A new idea: AI-animated videos of a project from the competition could compete. Greetings from Türkiye.

That′s a fantastic idea! Using AI to create animated videos of competition projects would be a brilliant way to enhance creativity and presentation (with extra points).

To ensure a level playing field, it would be incredibly helpful if you could create a small manual or publish an article on the origami.expert (blog or forum). This would guide all participants on the recommended tools, techniques, and scope for these AI animations. If such a resource were available, I would gladly add a link to it in the main rules of the Olympiad to ensure everyone has access to the same information.

Dear Friends,

Due to the large number of inquiries regarding registration issues, we have decided to extend the registration period by one day.

Unfortunately, this is the final extension we can offer to allow you to resolve any problems with your accounts. Please remember that creating an account on the website does not automatically register you for the Olympiad. After registering and logging in, you must go to the Olympiad page at

https://origami.expert/ioio/start/main

and submit an application, specifying the country you wish to represent.

Only after completing this step will you be officially registered as a participant.

Please personally verify that your profile appears in the list of participants on the following page:

https://origami.expert/ioio/start/participants

Once the registration period has ended, we will be unable to accommodate any further requests, and no additional delays to the start date will be granted.

Best regards,

The IOIO Team

I receive an error saying ″connection problems!″ when I click the register button after selecting a country. Monitoring the network traffic shows an additional message `{″error″:″bad_ajax″}`, but unfortunately that′s not much more helpful. I′ve tried multiple browsers and get the same behavior in each.
