- This is a national contest aimed at encouraging the best Sudoku solvers of India to participate and experience the excitement, thrill and puzzling atmosphere on the lines of various national championships and the World Championships.
- The championship consists of 6 online rounds (approximately one every month), based on different themes of Sudoku variants. The rounds are largely the same as the 2019 edition, in different order.
- Like previous years, the offline final will have a participation fee which will mainly be to recover venue/food costs. This fee will be updated a little later once the venue is confirmed. The online rounds will continue to be free for all.
- There are 3-4* spots for the Indian A team for WSC 2020, which will be decided by this tournament.
*Depending on whether the player awarded a wildcard from WSC 2019 participates.
- There will be a separate playoff at the end of the offline finals to determine the Mahabharat winner. There will be an eligibility criteria for this playoff, as explained below, to preserve the essence of Sudoku Mahabharat.
Offline finals: Registration process
- The process of filling up the offline finals' slots is the same as last year's process. We want to encourage solvers who aren't near the top yet but still want the experience of an offline final. The eligibility criteria is that the solver must have participated in at least 4 of the 6 online rounds ('participated' here means achieving a non-zero score in the round) OR reaches the top 60 within two or less rounds. After Round 6, we will ask the solvers from 1-30 first and give them a week to confirm participation. After this, registrations will be open to participants from 31-60 for a week, and then it is open to everyone 'eligible' by the criteria above, till we get to 60 participants. After that, due to venue restrictions, we will be ending registrations.
- The points total from the online rounds (i.e. the best 4 rounds for each participant) will be considered to give some base points to finalists to start with in the offline round. Specifically, the finalists will start with an average of their best 4 normalized scores.
- If online round organizers participate in the offline finals they will automatically get 100 base points.
