Goal
Light up every target with a beam of its colour. Drag pieces from the toolbox onto the board to bend, split and filter the lasers. Each level’s hint text introduces new pieces. Solving a level unlocks more, and the numbers in the level strip change colour as you go.
Mouse
-
Drag a piece between the toolbox and the board.
-
Click a piece to turn it anticlockwise.
-
Right-click (or Shift, Option or Control and click) to turn it clockwise.
-
Click a number in the level strip to go to that level.
-
Scroll over the game to change level (switch it off with the toolbar button).
Touch
-
Drag to move a piece. The piece floats above your finger and lands on the square it hovers over.
-
Tap a piece to turn it anticlockwise. A small wobble still counts as a tap.
-
On a touch screen, switch on Turn clockwise (the round arrow in the toolbar) and taps turn clockwise.
-
Hold the phone upright for a bigger board, and pick a level with Levels in the toolbar, or tap Next level after a win. Turn it sideways to see the whole original screen.
