Logic Masters Deutschland e.V.

This is my entry for turn 1 of season 1 of The Skunkworks League, hosted by damasosos92. In this round, the prompt was to create a puzzle using a given configuration of lines, where all lines must obey the same rules as each other and no other clues aside from given digits may be added inside the grid.

Rules:
Normal Sudoku rules apply.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.

If two orthogonally connected cells are both shaded, then they must have opposite parity (i.e., one cell must contain an even digit while the other contains an odd digit).

Clues outside the grid give the sum of all shaded cells in their respective row or column.

Along each given line, cells must alternate between being shaded and unshaded. Additionally, the sum of digits in shaded cells for each line must be equal to the sum of digits in unshaded cells on that same line.
