Thanks to Digg ( a online link sharing portal) found the link to this game. Engaging and could be additctive.If you think you are smart (or intelligent or great visualisor) prove it there!I ususally suck in visualising, but got enough score to be on the Top 20 ( almost everyone at digg seem to be in this bracket), lemme c if I can go higher.You know, I got a lot of free time.

And thanks to Digg again the game is interactive Tangram ( a chinese puzzle).Wiki reference: http://en.wikipedia.org/wiki/Tangram.
