Yes you like Tetris, I know you do. I haven't been watching you, it's just that I've never met anyone who doesn't like Tetris and I've met a lot of people. Hundreds of them. Simple Block is quite simply a flash version of Tetris for your mobile phone. Which is all it needs to be seeing as Tetris is one of the most amazing and addictive games anyone has ever played.
The games comes with a vibrating alert option when you do well and badly and multiple backgrounds, some of which are bizarrely coloured and get a little in the way of the gameplay. All the rules are the same. Keep building and eliminating lines, the game gets progressively faster the longer you play and you can preview your next piece in the right-hand side of the screen before it arrives. The game also learns your moves which makes it more difficult. You know the game; have fun.
Flash version of Tetris with all you'd expect and some annoying backgrounds.
