Kolkata is hosting the 19th World Sudoku Championship and the 33rd World Puzzle Championship from 11 to 18 October 2026. The event is being held at The Westin in Rajarhat and organised by Logic Masters India (LMI), the national representative to the World Puzzle Federation since 2008. Participants from 35 countries are taking part.
Championship format
The programme includes five days of competitive mind-sport events, with 38 rounds, more than 100 Sudoku puzzles and 250 other puzzles created by LMI. Sudoku is a number-placement puzzle commonly presented as a 9-by-9 grid divided into nine 3-by-3 boxes. In the standard format, each row, column and box must contain the digits 1 to 9 without repetition. Puzzle competitions can include different logic and deduction challenges, with formats set by the event organisers.
The 2026 puzzles include themes drawn from the Ramayana and the Mahabharata. India previously hosted the World Puzzle Championship in Goa in 2008 and Bengaluru in 2017.
