Normal Sudoku rules apply. Gray lines are between lines; the digits along the line must be strictly between the digits in the circles at the ends. A circle surrounded by four cells is a quadruple clue; digits in the circle must appear within the surrounding four cells.
Also, I believe my "lines plus quads" puzzles officially qualify as a series at this point, so if you're interested in prior entries, they include: German whispers, entropic lines, renban, and 10 lines.
Solution code: Row 2 followed by column 1

So much fun! Once you find the break-in, it flows quite smoothly. While each constraint works with the other beautifully, I especially loved the logic of the between lines. Thanks for setting twototenth!
