In 2008,the Olympic Games was held in China. We take "Water Cube"(short for "National Aquatics Center") as the theme,then creat a game according to the translucent construction. Click the "empty hole" in the picture, then the "empty holes" around it and itself will produce bubbles. But these bubbles are fragile, if you click them again, they will break up. At this time,you can think it over how you can fill the bubbles in the "empty holes" thus to achieve the final success. However,before you finish the game, you will find that the remained "empty holes" can not be filled with bubbles anyhow. Then you can try it again,your different thought may get a better effect.
