PLEASE NOTE. This is NOT a real puzzle. Don't try to solve it as a puzzle. It is a demonstration only of a technique

VERY IMPORTANT.... Some subscribers have told me they are not getting notification of when I upload a new video. YouTube has been working on this issue. I am pleased to inform all my subscribers that if you click on the bell at the right side of the red subscription button, you should receive a notification from YouTube that I will be uploading something new on a particular day and time.
*ATTENTION TEACHERS: A great resource. PowerPoint lessons, activities, and videos available in a teaching format on Teachers Pay Teachers https://www.teacherspayteachers.com/S...
I will only be putting up notifications once or twice a month.
One advantage of doing this on my channel is that when I premier a new video you have the opportunity to chat with me as well if you wish.
For frequently asked questions FAQ

When you have 3 or 4 or 5 or 6 or more empty cells in a row column or block this "outside the puzzle" procedure is VERY helpful.

Frequently when solving puzzles there are several paths to take to solve the puzzle. SO MUCH DEPENDS ON WHAT YOU SPOT AND WHEN. In this video there is a 3X3 of 2,3 and 5. which means you can remove all other small numbers of 2,3 and 5 in the rest of the row. This will also help you come up with a correct solution. Thanks to Jim W for pointing this out.
ALSO note that 8 can only go in column 3, because block 3 has an 8, column 5 has an 8 and column 1 has an 8. See lesson 13 "There's only one place it can go"

NEW you can now go to my web site and see an INDEX OF VIDEOS under strategy headings. Clcik on the number and it will take you to the video of interest.

Thought for the day : "There are several ways to cook an egg"
