Clue for Puzzle #205     What is your next move?  In box 5 we see that a 1 can exist as an option only in C4R6 and C5R6; therefore, a 1 cannot exist as an option in C7R6 or C8R6.  That leaves C8R4=1.

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.
