#sudokuguy #sudoku

In this tutorial I show the importance of 3 numbers in a row or column within a block and the resulting ramifications of TMB and LCR. This technique can be very helpful in puzzles of all levels.
At approx the 15 min point I cut to the end of the puzzle to save you time watching what has already been covered in previous puzzles as well to allow you to see the mess your puzzle may look like when you don't remove small numbers. Have fun.

To see a list of all lessons and tutorials go to:

Thought of the day. Smile.... it's good for the soul!

I have a suggestion with entering the small numbers. Use a different colored pen for the small numbers and another different pen for the resulting big numbersnumbers

at 4:35 as soon as you have the three numbers on the top row of the top left block, you can deduce the matching pair at the top of the top right block.
They have to be 1, 8 because all the other nimbers are used along the top row, even tho we do not yet know exactly where

and that means it has to be a 2 under the 7 in that block ... you got those another way around 14:00 :)
