In the standard form of this puzzle, you have to determine where to place two-sided mirrors at either or two diagonal directions in some cells, so that each pair of identical clues outside the grid is connected by a path of orthogonally connected cells through the grid which bends at (and only at) mirrors, in the directions which do not cross the mirrors. A path may use the same cell twice (either passing straight through an empty cell twice in different directions, or bouncing off both sides of the same mirror)
