This eighth puzzle is rated difficult like the seventh one, so get your thinking head on.
As before, you can resize your browser window to make the puzzle bigger or smaller as you want. To fill in a number that you definitely know, use your mouse to left-click on the square and select the number. If you're not sure but want to mark a possibility (for example, the 2 can either be here or here), then right-click on the square instead and select the number. This possibility will be written smaller and grey in the corner of the square, like a pencil mark to remind you.
The code running here is from the ActivityWorkshop, and the numbers were generated using the free (GPL'd) software
This example is coded as
N2x05-058 which means five level 2 rules are needed to solve it, and it starts with 58
empty squares. The extra level 2 rules bump the complexity up to difficult.
