About Sudoku Mahabharat 2022 - What's New?

This is a quick guide to what's new compared to last year's Sudoku Mahabharat.
  • 4 Rounds instead of 8. Everyone's best 3 scores will be considered in the final rankings.
  • 6 variants instead of 5 each round. To make up the numbers, 2 6x6 Classics instead of 4.
  • Rounds may be slightly more difficult than usual in terms of "Time Taken", and therefore slightly less finish-able.
  • Due to the Covid Pandemic situation, we will not be finalizing any details about the offline finals at this point. Any points below that are dependent on that are marked with ***. Since the offline registration process and the Prizes that we can give are contingent on this, those details have been removed altogether.
  • The base points from the SM Rounds will simply be the total score of participants. With just 3 rounds counted, this is a reasonable way to ensure that performance in online rounds is a significant part of doing well in ISC (as it will roughly count as one extra round proportionally).

Why the Changes?

The main reason for four rounds is we want a lighter schedule this year while we are restructuring and adding to LMI. Since it is just 4 rounds, having 6 variants per round makes more sense in order to explore more variants over the course of the series. Having 2 6x6 Classics instead of 4 still achieves the aim of having a warm-up for newcomers to get into the contest. This naturally means there will be that bit more to solve as a 6x6 variant and a 9x9 variant take the slots of the 6x6 Classics. As a general note, SM has a dual aim, i.e., a) providing something to solve for newcomers and casual participants and b) challenging India's top solvers and keeping them somewhat in touch with solving levels of a WSC. We can achieve both these goals without the rounds necessarily being finish-able for the top X or Y solvers, which is arbitrary anyway. Instead, what we will aim to do is, within the 6 variant pairs, we will try to have 2 easy pairs, 2 medium pairs and 2 hard pairs, so that there is something for everyone. We request the participants to consider this target when providing feedback for any given round. The other changes are hopefully self explanatory.
