Rules
Normal Sudoku rules apply.
Adjacent digits along a green line must differ by at least 5.
Digits along a pink line must form a non-repeating group of consecutive digits, but they may appear in any order along the line.
Each gray line can be divided into segments of contiguous cells, where the digits in each segments sum to 10. These segments cannot overlap and every cell is part of exactly one segment. Digits may repeat freely on gray lines and within sums.
Solution code: Row 1
