Google just started a game to label random images by players where they have to tag images in 90 second period and simultaneously other player will also tag it. If there is any tag match happens then their score points will move ahead.
The objective of game is to improve the quality of image search results by Google.
So if you have little time or like to have some fun then you must try this…. remember in this way you are helping Google to improve their search facility.
