The International Solving Contest next year will take place on Sunday 19.01.2025. 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 31.12.2011.
According the WFCC sanctions against Russia and Belarus because of the war in Ukraine only tournaments in category-3 are possible in Russia/Belarus.
According to the decision at the WCCC in Jūrmala, no cash prizes are permitted for all participating countries.
