This seems to be a Tetris Clone for both PC, mobile devices, and Surface tabs.
Not sure how good it is as I have not played it but really how much can one mess up with a Tetris clone?? ;-)
As is clear from the description programmed by non native English speakers so don't expect perfect English in game (which should be irrelevant though as everyone knows Tetris and how to play it).
From the website:
It is the world most attractive puzzle game, many people play Block vs Block II day by day never stop.
How to play this game? We are no need to explain. Everyone know it.
We offer a very powerful AI player playing with you.
Five years ago, we develop a First Generation game "Block vs Block", which has over 5 million download. This game "Block vs Block II" is improved version, we have rewritten everything. This game is using different game engine and we improve the graphic and AI.
Enjoy!
