When I bought my Sony Ericsson Arc S, this game was available as a demo and aroused my curiosity. Unfortunately, the demo was probably already expired, so I could never really play it. The greater the joy was then when it was offered as a "Free App of the Day" in the Amazon Marketplace. I downloaded it immediately and play it again and again. It has something to captivate the charm of Tetris with no time-consuming me to my smartphone. I highly recommend it!
