Sudoku Square Pattern 945 Horizontal

Another favorite pattern of mine is what I call the 945 Horizontal Pattern or 945 Non-diagonal Pattern. You can see a sample of it below.

 

I usually remember it as 945, 138, 276. And again, you can switch the order of rows or columns. And 945 can be vertical or horizontal. But once you find the 945 sequence in a row or column, then the entire square pattern should hold.
