Here is hoping that your first couple of weeks of 2024 have met your expectations!

Speaking of expectations, you can count on 48 challenging puzzles this year. (Editor says... WOW and great news.)

### Clueless?

We start with a Sudoku puzzle in progress, where it appears that there are no more obvious or not-so-obvious clues.  Can you find the hidden clue in Puzzle #181?   (I missed this clue the first time trying to solve the puzzle and the puzzle was not very cooperative.  I studied the puzzle as per below, and finding the clue, the puzzle was relatively easy to solve.)

How many Puzzles have you done?

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.
