Second Round of SOI 2026
The tasks of the second round of the Swiss Olympiad in Informatics 2026 are online!
Young computer enthusiasts can prove themselves and submit their solutions to our tasks until November 30. If you are one of the best participants, you’ll get the opportunity of winning prizes, a spot in our training camp in Sarnen, or even a ticket to the International Olympiad in Informatics in Uzbekistan in 2026.
The second round is split into two categories: Regular and Junior. This means that younger participants get the chance to start with easier tasks. Some spots in the Sarnen Camp are also reserved for the top participants of the Junior round. You can read more about that here and be sure to take a look at the participation rules on this page. Note that the use of AI is restricted!
If you did not qualify in the first round, there is still a chance for you to participate in this year’s SOI contest. By solving problems and getting points on the Pre-Round, you will be eligible to participate in the second round and qualify for future events this year.
You are welcome to attend one of our workshops! More information about this will follow soon.
Have fun solving our tasks!
