StopLight Puzzle

Turn all of the stop-lights to the same colour in 100 levels of this brain-melting puzzle.

Use different selections of lights and flip forwards and backwards through the light sequence until you can make them all either red, amber or green.

Each of the stages has three different 3x3 light selectors, so every one is a new challenge.

If you light lights out style puzzles then this takes things to the next level.
