The deadline for claims: 7th October, 2025
Director of the tournament: Torsten Linß (worldcupcomposing2025@gmail.com)
As of the deadline on 12 August 2025, a record-breaking 21 tournaments have registered for the 2025/2026 season of the World Solving Cup, including the Open Solving of the next ECSC and WCCC.
For the tournament to count for the WSC, the tournament director must send the invitation letter by email to roland.ott@gmx.ch at least two months before the event.
At the Congress in Alba Iulia the Rules of the WSC have been changed with a new Scoring System:
1. Elimination of the previous imbalance in the distribution of points between categories, which also leads to a reduction of points awarded in the Open Solving of the ECSC and the WCCC.
2. Increased minimum scoring for the winner of national WSC tournaments to 10 points by reducing the number of WSC Categories from 14 to 10.
The main goal of these changes is to reinforce the original idea of the World Solving Cup, which is for participants to take part in tournaments outside their own country. This is intended to encourage top solvers in particular to participate not only in their national championships and the open Solving of the ECSC and WCCC.
WSC calendar for the season 2025/2026 | WSC rules as of 2025
The International Solving Contest next year will take place on Sunday 25.01.2026. The event is happening simultaneously in all participating countries.
There will be three categories: one for experienced solvers. The second category is intended for weaker, inexperienced solvers. This second category is not open for solvers with a rating (or half-rating or non-active-rating) of more than 2000. The third category is intended for youngsters born after 31.12.2012.
According to the WFCC sanctions only tournaments in category-3 are possible in Russia/Belarus. According to the decision at the WCCC in Jūrmala no cash prizes are permitted in participating countries.
Separate results are recorded for youth, females and seniors. For Categories 1 and 2 the results of solvers will be rated. However for all solvers no norms for titles are possible.
The name of the locally appointed controller must reach the central controller by email not later than 31.12.2025: arvydas.mockus@gmail.com

This is a formal document issued by the WFCC Ethics and Disciplinary Committee
regarding disciplinary action on 4 solvers from Azerbaijan.
Following protests submitted by six countries and the evidence from reports (Points 9.1 to 9.5 in WCCC 2025 Agenda), WFCC Assembly voted to exclude results of the four Category 1 solvers from Sumgait (Azerbaijan). Consequently, the rating lists for April and July 2025 have been slightly changed. Here are the final results of ISC 2025 as approved by the WCCC 2025:
Results Report & Summaries – CAT 1 (180 solvers) – CAT 2 (254 solvers) – CAT 3 (292 solvers)
