Well, I can. Its already half-done.
Its based on logic, rather that hit and trial, so It WONT be able to solve hit and trial Sudoku. It will be able to solve only logical sudoku, like those in Delhi Times and The Hindu.

I have also written 9X9 sudoku. Yes i can make 16X16 and 25X25 as my program uses only 1 technic to solve. Earlier i was thinking that i might have to create different functions for diffferent technic for solving it, ironically i wrote only 1 function and it is able to solve the whole sudoku. It uses simple elimination technic in a box, and then it keeps on repeating the same process for other 3x3 boxes till whole sudoku is solved. For making 16x16 and 25x25 sudoku, I just have to replace all 9 with 16 and 25 and it will be able to solve it. By the way i wrote the program in VB6.0

Don't answer that! I have stepped into the world of Programmers and Mathematicians!

Hi Guys,

Best of luck to all generators and solvers.
By the way, I am also making a SUDOKU SOLVER. Like Abhishek, I use the same technique irrespective of 9, 16. 25 sudoku's.

By the way, Abhisek, it is 'technique' and not 'technic'.
