Tetrisphere

Once you grasp this, and it takes a few minutes, you can start destroying large amount of blocks at once. You’re helped by the ability to drag blocks where you want – as long as there aren’t any in the way of course – and the helpful fact that the shadow of the block you’re about to place changes colour if it will start a combo. It’s hardly a pick up and play title. But credit to developer H20 Interactive, they tried to squeeze as much as they can out of the concept. There’s a two player mode (strangely, none of my friends want to play the game), and a solo option with plenty of options.
