Okay - you need to a combination chain of 6 or more, and the LAST move has to be vertical. This always gives a vertically charged light. You need to get 3 vertically charged lights to knock out the 3 blocked squares, and then 3 more vertically charged lights to bring the masks off the board. But if you are VERY VERY lucky, you can go for a horizontal charge after unlocking all, and if that just happens to land on the light that is keeping the masks from dropping, then you can bring down all 3 with one more vertical light aimed at the horizontal light. Good luck!
