It has been years since I wanted to create a computer game for this brain twisting tangram. Though not perfect, still I consider it fully working as it is playable already. :)

I just never imagined JavaScript will be the one I'm using to implement this game.
By the way, this game is best played using Firefox but it also works on Chrome & Opera.
