partial answer check only)
Place the numbers 2, 3, 4, 6, 8, 9, 12, 16, and 18 into the grid following traditional sudoku rules.

There are four subway lines: 2, 3, 4, and 6. It is up to the solver to determine which color/shape is which line. The white hexagon stations serve multiple lines.

Every number in a station (outlined shape) along a line must be divisible by the line number. Numbers may repeat along a subway line so long as the placement does not violate traditional sudoku rules.

The numbers along a line between stations must NOT be divisible by the line number, AND they must be between the values of the two adjacent stations.

Solution code: Enter row 7 from left to right, then column 9 from top to bottom, with no spaces or symbols between the numbers.

I've spent some time trying to understand the rules. You just insert the 9 numbers — 2, 3, 4, 6, 8, 9, 12, 16, and 18 — into the whole grid, instead of the usual 1–9 in regular Sudoku. It's not as complicated as it looks. It's about 3 to 4 stars in difficulty, or maybe just 3 stars if you understand it properly. The puzzle is well-designed. I hope you try it and enjoy it.

I don't believe the SudokuPad version will work because this puzzle uses numbers larger than 9.

Converted to CTC https://sudokupad.app/qjfbpzx7wq

Edit: It doesn't matter if the solution check works or not. I'm just more used to SudokuPad's interface, and I can just input small numbers or letters to help me solve this.
