- Normal sudoku rules apply.
- Slightly modified curve data puzzle rules apply: draw lines that connect cell centers horizontally or vertically, such that every cell is connected to one or more cells with a clue. The shape of lines connected to a clue must be like the clue in that the relative position of horizontal and vertical segments and turns must be the same, without rotations or reflections. The lengths of straight segments may vary, but must not be 0.
- Digits in the circled cells are curve data clues (e.g. if there's a "5" in the circle, then the clue is in the form of "5" - see the image to see the forms of each digit).
- All circles are given: if a digit in a cell is not circled then the line that contains it can't be in the form of this digit.
- Please note that unlike regular curve data puzzles, a line could go through more than one clue, but only through the clues of the same form. In other words, a line could go through several circled cells, but in this case all these cells will have the same digit.
Solution code: digits of row 2, from left to right

Great puzzle, the first curve data variant I actually enjoyed! It makes great use of some commonalities with the shapes of digits.

Great puzzle, never done a curve data before so this was pretty challenging for me.

so, a circled 1 cannot have only one cell. but you also remind me it's kind of rare to see a curve data puzzle here. thanks
