Qubed is a new puzzle game for the iPhone, iPad and iPod Touch by The Blu Market. Think of it a bit like a cross between 1010! and Tetris. You place various pieces onto the board while trying not to block yourself from adding more pieces, and you can clear lines like in Tetris in order to make more space.
When I first played this game, I was a bit confused about it. I always lost without knowing why. Thanks for these tips but I think Tetris is better than Quebed.
