About Sudoku Mahabharat 2016-17

Logic Masters India (LMI) is conducting the Indian Sudoku Championship (ISC) 2017 (tentatively) in July-2017. Like 2016, the qualification for ISC will begin early, from January 2017 onwards, in the form of Sudoku Mahabharat online rounds. The structure is different this year, read on to find out more.
  • 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 4 online rounds (one every month), based on different themes of Sudoku variants. In 2016, we had 8 online rounds with 8 different themes. These 8 themes will be repeated this time, but each round will feature two different themes together.
  • Like last year, this 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 4 spots for the Indian A team for WSC 2017, which will be decided by this tournament.
  • 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: New registration process

  • There is a change in the way the offline finals' slots are filled up. 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 3 of the 4 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 4, 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 3 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 3 normalized scores.

Prizes

All players who appear for the offline finals will receive a certificate.
Additionally,
  • Top-3 players at the offline finals will be awarded medals / trophies.
  • Top-10 players at the offline finals will be awarded prizes in the form of LMI merchandise.
  • All players at the offline finals Under-21yrs and over-50yrs will receive special prizes.
  • All players travelling from other countries (non-Indians), will receive special prizes.
