Tetris is a free tile-matching video game that uses tetrominoes, a type of polyomino with four elements. This game has been popular since its inception and was adapted from previous puzzles that used polyominoes, which have been used in popular puzzles since 1907.

In Tetris, players must manipulate tetriminos, which are game pieces shaped like tetrominoes, to create a horizontal line of ten units without any gaps. When a line is created, it disappears and any block above the deleted line will fall. The game progresses by increasing the speed at which the tetriminos fall, and each level requires a certain number of lines cleared to advance. The game ends when the stack of tetriminos reaches the top of the playing field and no new tetriminos can enter.
There are different types of tetriminos, all capable of single and double clears. The I tetrimino is the only one that can clear four lines simultaneously, which is called a "tetris". However, this may vary depending on the specific Tetris implementation and its rotation and compensation rules.
Overall, Tetris is a fun and challenging game that has stood the test of time. Its simple yet addicting gameplay has inspired various adaptations, such as Tetris serving dishes and playing the game on the sides of buildings.
