Clue for Puzzle #197    What is your next move?  In box 4 we see that C2R5 & C3R5 are limited to options 2 & 6; therefore, a 6 cannot exist in C4R5, C5R5 or C6R5.  In box 8 a 6 can only exist in C6R7 or C6R8; therefore a 6 cannot exist in C6R4, C6R5 or C6R6.  Therefore, the only cell in box 5 that can be a 6 is C4R6.  C4R6=6.

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, we 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.
