ISKL - Indian Sudoku League

About ISKL

Indian Sudoku League (ISKL) has launched a nation wide concept of Developmental Ranking System for Sudoku. The Indian Sudoku League has the creative assistance of Logic Masters India(LMI). LMI will be hosting the online rounds and providing content for the event.

Mission of ISKL

  • To provide a competing platform: It has always been a challenge every year, to select talents for the World Sudoku Championship. The difficulty constraints have always provided an obstacle for establishing a remarkable National wide event of a greater reach. There has always been a discussion and fruitful difference of opinion with the National Selection procedure. Easier competitions encourage newcomers while challenging competitions help us to select a worthy National team for the Annual World Championships. It was to this end that LMI began Sudoku Mahabharat, but when ISKL approached us with their own goal to have a nationwide tournament, we thought we could use this concept to go one step further in talent development, and make a system which casts a wider net on upcoming Sudoku talent in India.
  • To provide a relative National Ranking system: National ranking system will go a long way in upbringing and nurturing national talent with greater emerging competition. It will give all the participants a national ranking which can be upgraded every year with sharp skills and sheer hard work.


View ISKL as a standalone league whose goal is to develop and build new talent by providing a training element to it. Over the years, the Sudoku community has a few regular members competing throughout the year, learning and exploring all the aspects of the competition. This has led to those few individuals becoming heavily experienced and developed and has caused a gap between them and newcomers who find it difficult to get motivated because of this gap. While ISKL will be conducting a Nation wide gung ho sudoku league and awards, LMI offers an opportunity for top 10 selected solvers to learn from the core team/experts. The top 5 Inexperienced* Above-18 participants and the top 5 Inexperienced Under-18 participants will be added to a private group where they will get training, insight and tips from India's crème de la crème talents, who have been to the World Sudoku Championships and have been among the World's top-20 Sudoku finalists. Using this learning experience, we hope to bridge the gap for some newcomers to make it to the next level. There will also be a wildcard entry for the winner (1st place only) of ISKL into the Indian B team for the World Sudoku Championship for 2017, which will be held in Bangalore and hosted by Logic Masters India.

*The criteria here for inexperienced is as follows:
- The participant has not participated in a World Sudoku Championship.
- The participant has not achieved a top-20 position in an Indian Sudoku Championship.

  • There will be 3 rounds, on the weekends of 4th December, 11th December and 18th December. By 'weekends', it is meant that the contest will be open for registered participants from Friday morning ~9 AM to Monday night ~ 9 PM.
  • Round 1 will have easy Classics, Round 2 will have medium Classics and a few introductory 6x6 variants, and Round 3 will have easy-medium Variants.
