Tetris

Tetris is a puzzle game in which small squares of different shapes fall from the top of the screen in turn, and the player adjusts the position and orientation of the tiles so that they spell out one or more complete strips at the bottom of the screen. These complete bars disappear to make room for newly fallen tiles, while players are rewarded with points. Blocks that have not been eliminated are constantly piled up, and once they reach the top of the screen, the player loses and the game ends.

=== Description of the Qualifying ===
The dan rank is used to measure the player's game level, which is a more realistic reflection of the player's strength, and the higher the dan rank, the higher the strength. In online matches, players are automatically matched with the closest opponent to ensure a 50% chance of winning.
There are six ranks:
* The bronze rank is divided into two small steps, each with two stars
* The silver rank is divided into two small steps, each with two stars
* The golden rank is divided into three small steps, each with three stars
* The platinum rank is divided into four small steps, each with four stars
* The diamond rank is divided into five small steps, each with five stars
* The king rank is not divided into ranks, and the stars accumulate
=== Four-person brawl ===
The four-player brawl mode is a more exciting way to play, where four people are randomly matched, attacking opponents in a loop, switching attack objects every 8s until the final survivor is decided.
For example, ABCD has four players in a game, and at the beginning A attacks B, B attacks C, C attacks D, and D attacks A. After 8s, the attack object rotates and switches to A attacks C, B attacks D, C attacks A, and D attacks B.
