How it works You will see a set of cards with the face down. You need to use your mouse and click on one of the cards. After that you need to click on another card. If the cards turns to green that means you have found two cards that match. This means that you have matched an image against its chinese word in Hanzi-Image mode or that you have matched the chinese character against its chinese pronunciation if you are playing in Hanzi-Pinyin mode. There is a time constraint on this exercise so try to be quick!
