Tetris is a classic Russian game, I trust that you have already been familiar with it. Its method is so interesting that you still want to play it. So I decide to recommend this game again. When the block is dropping, you could use a direction keyboard to make it rotate and move right or left. If they fill in one line, the blocks on this line will disappear. The high level the blocks will drop faster, so you should keep the brain running quickly. When anyone touches the top of the screen, game over.
