World Memory Game 生字遊戲

If teachers want to give students a quick check to see if their students really "learned" those vocabulary, here comes a good Memory Game, which include both fonts (traditional and simplified), different patterns: Match character with either Pinyin or English definition. 

It leaves me one reason that I should provide it to my students;
It is FREE!  
more than that, it works out just great with iPad, 
(no extra flash software required)

therefore it is also a good choice to do it in the class competition game,
(especially for whiteboard frequent user)
