Normal Sudoku rules apply. Additionally:

1. Numbers along pink lines (r1c1-r9c9, r9c1-r1c9) each form a consecutive set of non-repeating digits (like a Renban line) and no two high digits (from 6798) or two low digits (from 1234) may be consecutive on the lines.

2. Digits in cages do not repeat. The totals of cages joined by pink lines differ by the difference of the two adjoining digits on the line. For example, if r2c2 was a 3 and r3c3 was a 7, their cage totals would differ by 4. Either cage could be the larger cage total.

3. Cage total differences (larger total minus smaller total) cannot repeat on the same line. So, if the difference between the totals of the cages at r1c1 and r2c2 was 3, no other cage total difference, on that line, could be a difference of 3.
