This is mainly a variant combination of Renbans and parity that I liked when I worked out the possibilities. Testing suggested about 3 stars, although one tester solved it in under 15 minutes, so some will find it easier. Please enjoy.
Rules.
Classic sudoku rules apply.
Cages total to the value shown in their top left corner.
Cells with grey squares contain even digits.
Cells separated by white circles contain consecutive numbers.
On every yellow line, there is exactly 1 contiguous parity renban (a set of consecutive even or odd digits from 2468 or 13579, in any order), whose digits sum to half of the yellow line total. It is also the only parity renban on the line.
For clarity: Example valid sequences are; 1(24)5 and 6(153)3. 926421 is not valid, as this has more than 1 contiguous parity renban possibility - 9(264)21 and 92(642)1.
