Rules
Normal sudoku rules apply.
- Train Lines: The total value of each coloured line is equal, and each coloured line contains at least one Station Cell.
- Station Cells: There are 9 station cells, all located along the lines. There is one in each row, column, and box, and each contains a different digit. The real value of a station cell is calculated by doubling the digit that appears in it.
- Barriers: A barrier splits a line into sections. The total values of those sections differ by exactly 1.
- Trains: For each train placed on a line, the two cells immediately next to it on that line sum to a multiple of 5. All valid trains along the lines have been placed.
Have fun!
