- Normal sudoku rules apply
- Digits on a line either sum to the value outside the grid (some to be determined by the solver) OR represent the same value in binary format (see below) in their respective row/column. Note that for any line it is NOT permitted for both to be true and all lines are completely horizontal/vertical
- When determining the value of a 'binary line' odd digits are read as 1 while even digits represent 0. The value is then read as a binary number from left to right or top to bottom e.g. 8574 on a such a line would be equivalent to 0110 which gives a value of 6
Solution code: Row 4 and Row 6

Great maths-centric puzzle, I found it hard at quite a few places due to the dual nature of the rules, like a truth/lie puzzle, but it was always possible to deduce my way through.
- Many thanks for solving; glad you worked your way through it!
