Rules:Paint some cells black to create a continuous wall.Number/s in a cell indicate the length of black cell blocks on its neighbouring cells.If there is more than one number in a cell,there must be atleast one white cell between the black cell blocks.Painted cells cannot form a 2x2 square or larger.There are no wall segments on cells containing numbers.
Identical cells in every pair of identical outlined regions must one be shaded and the other unshaded.All such pairs of outlined shapes are asymmetrical.
If, for example ,the corner cell of an "L" tetromino is shaded ,then the same cell in the other "L" tetromino must be empty.This applies to all cells of the shape.
Puzzle modified for uniqueness.
I'm finding R1C7 as well as the pair R1C1 and R7C4 to be undetermined.
