Sudoku Mahabharat Episode 7 by Logic Masters India (LMI)

Episode 7: Converse Round

Instruction Booklet : Click here

Finally a long awaited moment for me, where I am the author for this round. This is the last episode of long going Sudoku Mahabharat started in September-2014. So pull up your sleeves and get ready for one last battle to make your place into offline finals which will be held on 10th May 2015 in Bangalore. For more details on Sudoku Mahabharat click here.

Although you can go out in the internet world and get as many Sudokus as you can but i am also sharing some of the links for your practice. Also sharing some of the tricks to tackle some of types appearing in this test.

Added some new tricks on 19th march 2015 (it's in red color)

Tips and Tricks: 

1) The foremost and biggest tip is don't forget what is the name of this round. Pun not intended.
2) Average Sudoku - Remember since it's average and only integers are allowed, numbers on both side of line will be of same type. i.e. Either both numbers will be even or both will be odd. Also observe 1 and 9 can never be on the lines (1 and 6 for 6x6). 
3) Kropki Sudoku - Black dot only possible pairs are 1-2,2-4,4-8,3-6. White dot pairs are 1-2,2-3,3-4,4-5,5-6,6-7,7-8,8-9. If you have series of 2 black dots then only possible sets are 1-2-4 and 2-4-8. And the only 3 consecutive black dot series is 1-2-4-8. Remember order of these sets can be either way. Also 1-2 can contain either dot (just a reminder). Do not restrict to this as for e.g. if dots series are in L shaped then it can have repeated digits as well like 4-2-4 etc. If you have 4 black dots in the 3*3 box entirely, or in a row or in a column then remaining 3 cells (that do not share dot) will contain digits 5,7,9.
3) Consecutive - Try to look out for big series.
4) XV - V pairs are 3-2,1-4. X pairs are 6-4,7-3,8-2,9-1. Clearly 5 doesn't fit in any of these so now you know what to watch out for.

Practice Puzzle Links:

Anti knight:
Average Sudoku Variants: (Note: these are variants and not the actual Average Sudoku rules used in the test - but will provide you with good practice for this type)
XV Sudoku:

General links: (Average Sudoku especially along with few other types as well) (IB and PB)

Well once again, these links are just glimpse of what is available out there.
Hope you all will enjoy the Sudoku's.
Have fun :) 
Good Luck !!! :)
