Math round of Sudoku Mahabharat has ended.A total of 41 completed the set and many had come close to finishing the set.Congrats !

As most of you had noted, Little Killer (9X9) is a hard sudoku and is without doubt the toughest of the set.I hope the points allotted justified the same.The solve path is very narrow.Rakesh liked it very much after test solving and in the end preferred it over Mathrax which was also in the pool of sudokus but did not make the final cut. The decision to include LK seems to be correct as most of the other sudokus were of a manageable difficulty level and solvers had to really overcome this tough sudoku to finish the set.

I hope everyone had fun solving the sudokus and thank you to all who had given their feedback ! Thanks to Akash for contributing the bulk of sudokus and to Rakesh for running things smoothly behind the screen without any hiccups !!

Congratulations to Jakub , Tantan & Kota for finishing in top 3 and also Prasanna , Rohan & RIshi for taking the top 3 spots among the Indians.

Coming back to the sudokus , I had created 6 variants and Kishore created 2. Out of this 4 of mine were selected and 1 of Kishore's was selected. My little killer lost out to Kishore's little killer ( for obvious reason - although very difficult , it was a beautiful puzzle ). Kishore had also made a Mathrax but that was too difficult to be included . Two of my sudokus that did not make it were Little killer and Group sum ( you can find them on my blog ).

You must have noticed that all the grids were numberless. I wanted the theme of the test to be Numberless and asked Kishore to create keeping this in mind. I hope we succeeded in creating a good set. As an author , my personal favourite was 9x9 Killer. Kindly share your feedback on the forum.
