The fun in Sudoku is in figuring out the solution to the puzzle without assistance from anybody or any software. I really don't understand why people bother with short cuts for such an intellectual game, Doesn't it defeat the aim?

If you're a lover of Sudoku and you'll like to show yourself, come here let's discuss it and share strategies. I hold a record of 19 minutes 35 seconds solving 56 empty cells of a 9x9 grid. I play with AI Factory's Sudoku on playstore because it's timed, is light weight, has quick notes, and 1500 games on 5 levels of difficulty.

I need a challenger here.
