Clue for Puzzle #157 …  did you find the clue?  If not, read on.
In box 8 we can see that C4R9, C5R9 & C6R9 cannot have options 3, 6 or 8.  Check out column 2.  C2R9 cannot have options 3, 6 or 8.  That leaves C3R9, C7R9 & C8R9 only having options 3, 6 and 8.  There is already a 6 & 8 in column 8; therefore C7R9=3, and so forth.

You may want to finish solving this puzzle.  Advance techniques (6 & 7) are not required.

## Important Editor's Note

I have to admit I took double take when I saw the numbers this month for we are now at #160!!! Do you solve them each month? Dan would like to hear more from his readers, such as questions, comments & suggestions - info@thousandislandslife.com.  We will forward this to Dan, and he will contact you directly.  Thank you."

Recently someone wrote to ask how to fill them out online. Unfortunately, you need to print them yourself,  but that is easy to do and I know you will have just as much fun. Also you can use a grid sheet and copy numbers onto the grid.

And, if you have not already done so, I suggest you purchase Dan’s book: “3 Advanced Sudoku Techniques, That Will Change Your Game Forever!” Purchase of a book includes a 50-page blank grid pad, 33 black and two green tokens. The book is available by contacting info@thousandislandslife.com.

Be sure to read the TI Life's review of Dan's book by Jesse Kahn published in Jun 2015.
