National Championships
Two national championships are organised every year to select the Indian teams for the World Championships. Typically the the Indian Sudoku Championship is held in January-February each year to select the team for the World Sudoku Championship. The Indian puzzle team is selected through the Indian Puzzle championship which is held each year in August-September. The Indian Sudoku Championship 2010 was organised in association with TechFest at IIT Bombay on 24th January 2010 to select the Indian team for the World Sudoku Championship 2010 to be held in Philadelphia, USA.

College Fests
To encourage puzzling and sudoku activities, we have associated with various colleges to organise puzzle and sudoku championships as part of their college fests

Mock Tests
Mock tests are organised by the members of the Logic Masters Community. The mock tests serve as practice material for the participants at the national championships. They are also aimed at encouraging the art of creating puzzles and sudokus.
