Sudoku Square Patterns 357 Horizontal Pattern

Another favorite pattern of mine is what I call the 357 Horizontal Pattern or 357 Non-diagonal Pattern. You can see a sample of it below.

I usually remember it as 357, 694, 812. And again, you can switch the order of rows or columns. And 357 can be vertical or horizontal. But once you find the 357 sequence in a row or column, then the entire square pattern should hold.
