Normal sudoku rules apply. Digits in a cage must not repeat and sum to the number in the top left corner (if given). Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area can be entirely shaded or unshaded. All cages have 1 shaded cell and 1 unshaded cell. The largest digit in a cage is always shaded and the smallest digit is always unshaded. ALL GIVEN DIGITS ARE OF THE SAME SHADING. Digits separated by a black dot are in a 1:2 ratio.
