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.

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:
