紅燈綠燈（免費(fèi)）

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! 你能得到所有的燈是綠色的，在相同的時間嗎？點(diǎn)擊一盞燈，將改變其顏色，但所有連接到它的鄰居燈光的顏色也會發(fā)生變化。通過綠色，黃色和紅色的顏色，就像一個交通燈的燈循環(huán)。這是一個非常具有挑戰(zhàn)性的難題，所以不要感到驚訝，如果它需要你更多！
