whoamI asked:
Anybody have any techniques to figure out the medium, hard and very hard Sudoku puzzles? I know how to get the very easy and easy, but the others I can’t. Any tips besides what is on the Sudoku website? That doesn’t help with the more challenging ones.

I love sudoku!
Some can be tough.
I deal with the “tough ones” in two ways:
~ if there are three spaces available, which 3 numbers can fit there, are they any where else in the nine space that you need?
~ get up and walk away. come back in a few minutes and VIOLA! An answer is right there, even though you couldn’t see it earlier.
