Parity Party II

Normal Sudoku rules apply.

»Little Killer« Rules: A number with arrow indicates the sum of cells along a diagonal. Digits may repeat within that diagonal (unless they're in the same box, of course).

»Parity Party« Rules: A number at the edge of the grid indicates the sum of cells encountered when moving through the grid from that vantage point, UP TO AND INCLUDING the first odd or first even digit. For example, a 15 at the bottom of a column could indicate something like 7-8, 8-7, 1-3-5-6 or 2-6-4-3 (among others) when reading up that column... but not 1-2-3-4-5 or 2-6-3-4 etc. That is, the parity of the farthest digit must deviate from that of the others.

Note: If the clue is less than 10, it might simply indicate the value of the first cell. That is to say, you could be adding up zero odd and one even number, or vice versa.

The givens in the grid were pushed together slightly to make them look like two-digit numbers. This is purely decorative and has no influence on the solution path.

Penpa version, with embedded solution checker.

As a gentler introduction into the 'Parity Party' genre, I recommend Parity Party Kidoku.
