The 2023 World Sudoku and Puzzle Championships are open to anyone interested in spending several days solving hand-crafted logic puzzles in a competition setting while meeting many fellow puzzlers. Official competitors qualify through their national puzzle federations, but unofficial spots are open to those who are able to cover registration fees (see our FAQ page for more detail).

Registration is now closed.


Summary of fees and what is covered

The default room selection is a double (2x) with two double beds, and we have prioritized lowering the cost for this option in setting up the event. Triple and Quadruple rooms start with having the same two beds but may be able to have an additional roll-away bed depending on availability.

Per person cost, in Euros*, for A team members + Captain or for WPF Personal Members on UN teams. Note that being an A team member for either the WSC or WPC qualifies you for the discount price for both events so this discounted rate can apply to a maximum of 8+1 people per country.

Both events €850 €765 €720 €1220
