I always love a new challenge. Once you get the lines of sequence, the puzzles solve pretty smoothly. Some of the straight lines(between the dots) are hard to tell exactly which spaces to fill. They criss cross the puzzle or go up the side. I just take a moment and follow the course of the line with my finger.

I first came across this version of sudoku on a return trip from Hawaii. My husband purchased it for me in the airport, knowing I enjoy playing. It a fun & different sudoku variation that I enjoyed so much, I looked for it online to give to my father-in-law. He loves it!
