红灯绿灯（免费）

Can you get all of the lights to be green at the same time? Clicking on a light will change its color, but will also change the color of all of the neighbor lights attached to it. The lights cycle through the colors green, yellow, and red, just like a traffic light. This is a very challenging puzzle, so don't be surprised if it takes you many more! 你能得到所有的灯是绿色的，在相同的时间吗？点击一盏灯，将改变其颜色，但所有连接到它的邻居灯光的颜色也会发生变化。通过绿色，黄色和红色的颜色，就像一个交通灯的灯循环。这是一个非常具有挑战性的难题，所以不要感到惊讶，如果它需要你更多！
