How do you tackle a sudoku puzzle? (lemmy.ml)

When you first crack open a new sudoku puzzle, do you look at the rows or columns first? Or do you work in blocks? What's your strategy?

I start with 1s, look in the row blocks to see if I can fill any, then the column blocks. Then move on the 2s, 3s... If a block or row or column is mostly filled in I see if I can get any of the rest to close it out.

This only gets you so far. The more challenging puzzles require you to think ahead and make assumptions.
