Complete Results


  1. Hey,
    Your performance was above par and simply exceptional.

    The minimum time I took to solve any of the classic sudoku mentioned there was > 15mins.
    Is there any particular strategy you follow while solving those or does it depend upon practice?

  2. there is no particular strategy i suppose...atleast i don follow any... i also took part in this championship held during techfest and was in the top 40
    i have been solving classic sudokus but was new to the others but could solve it... so i guess there isn't any!
    may be for better speed ur brain should work fast which in my case is slow!

  3. @Aman..
    No strategy... :( Practice should help I think..
