Normal sudoku rules apply. Shade a single group of orthogonally connected cells in each dashed cage. Shaded groups may not share a dashed border. Each cage must contain at least one shaded cell, and two cages which share a border cannot contain the same number of shaded cells. Digits MAY REPEAT in cages. Some cages have one or two sums indicated. The first value given is the sum of all digits in shaded cells in that cage and, if given, the second is the sum of all digits in unshaded cells in the cage. A cage sum given as "X" is to be determined by the solver and is the same value in all appearances.
