It may seem like just a few numbers in a square grid, but for us, Sudoku is a passion we want to share with the world. We are a non-profit organization full of volunteers who organize the European Championship and build community in their free time - evenings, weekends, and after work.

We want to give players the thrill of a high-quality solving while showcasing that world-class competitions can happen right here in Bratislava. Sudoku is what connects us to the rest of the globe; we represent Slovakia at international tournaments, competing against the very best—and now, we look forward to welcoming them here.

How can you help? Every contribution you make is like a correctly placed number in a Sudoku grid – it moves us forward. Your donations will support the organization of the 2026 European Championships, Slovak regional tournaments, and our national team, ensuring that Slovak puzzling continues to be heard far beyond our borders. Thank you for helping us put this story together. Every euro counts!
