Normal sudoku rules apply. Yin Yang: Shade some cells such that i) all shaded cells are orthogonally connected; ii) all unshaded cells are orthogonally connected; and iii) every 2x2 contains both shaded and unshaded cells. Yin Yang Split Lines: Yin Yang borders split lines into 2 or more segments with the same sum. (If 2 cells are adjacent along the line, they are in the same segment if and only if they have the same shading). Digits may not repeat within a segment. Every line contains shaded and unshaded cells. Segment Counters: A digit in a circle on a line indicates how many total segments that line has.
