RULES:

Normal sudoku and yin-yang rules apply

A cage is a group or orthogonally adjacent cells. Cages exist in the grid, and their exact location and orientation must be deduced by the solver. Digits can't repeat in a cage and all cells in a cage are either all shaded or all unshaded. No two cages can share a cell and no two cages can be the same size. The sum of the digits in a cage is the amount of cells of the cages shade "seen" by the cage. Opposite shading blocks sight. Blue dots indicate that two cells are in the same cage.

Pink lines are renban lines, the digits on renban lines can be rearranged into a set of non-repeating, consecutive digits. All renban lines are half one shaded and half unshaded.

Black kropki dots seperate digits of a 1:2 ratio that are of opposite shading. White kropki dots seperate consecutive digits that are of the same shading. Other possible locations for kropki dots may exist in the puzzle.
