- Normal Sudoku: Place the digits 1-9 in each row, column and box, without repeats.
- Quadruples: Digits in circles have to appear at least once in the 4 surrounding cells.
- Ten-line: Divide the gray line into segments. The digits on each segment sum to 10. Digits may repeat on a segment.
Solution code: Column 1

Some parts got a bit tricky and there were often deductions to find in surprising places, but I really appreciated the interactions between two less common and more complex constraints. Overall an interesting and enjoyable challenge!

A great flow to the main line, but also a great sudoku ending for the puzzle. I really liked this a lot.
