Logic Masters India invites everyone to participate in Sudoku Mahabharat, a series of Sudoku contests. Similar to last year's Sudoku Mahabharat, each contest will have a certain theme to it that categorizes the puzzles appearing in the contest. This year, there will be two themes per round, in a reduced format of four rounds, with 3 variants of each theme totaling to 6 variants per round.
Here are the dates, for each of the rounds.
Standard & Neighbours - 6th to 9th January
Odd Even & Twisted Classics - 3rd to 6th February
Outside & Math - 3rd to 6th March
Irregular & Converse - 7th to 10th April
