The championship theme will be the "Mahabharata"
The competition rounds of the 19th World Championship will be dedicated to the characters and events of the ancient Indian epic "Mahabharata".
The organizers have prepared 18 thematic episodes telling the stories of the work's heroes and the key events of the plot. These stories will serve as the basis for the design of the individual rounds of the championship. However, knowledge of the epic will not be required to solve the puzzles.
Detailed rules, sudoku variants, and the structure of the competition rounds will be published in the official instruction booklet closer to the start of the championship.
