Tetris:
Plates of different shapes composed of small squares fall from the top of the screen one after another. Players can make one or several complete pieces at the bottom of the screen by adjusting the position and direction of the plates. These complete bars will disappear immediately to make room for the newly fallen tiles, and at the same time, the player is rewarded with points. The blocks that have not been eliminated continue to pile up. Once they reach the top of the screen, the player loses and the game ends.
The author believes that many friends have played or heard of this little game. Today, the author will take you through the writing process (the writing time is a bit long, there may be some oversights, and criticisms and corrections are welcome).
