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.
