How to play Tetris online?

Tetris is a tile-matching puzzle computer game designed by former Soviet engineer Alexey Pajitnov in 1984. Here you can play the MS-DOS version of this famous game online for free. Tetris is primarily composed of a field of play in which pieces of different geometric forms, called “tetriminos”, descend from the top of the field. During this descent, the player can move the pieces laterally and rotate them until they touch the bottom of the field or land on a piece that had been placed before it. The objective of Tetris is to use the pieces to create as many horizontal lines of blocks as possible. When a line is completed, it disappears, and the blocks placed above fall one rank. Completing lines grants points, and accumulating a certain number of points moves the player up a level, which increases the number of points granted per completed line. If the player cannot make the blocks disappear quickly enough, the field will start to fill, and when the pieces reach the top of the field and prevent the arrival of additional pieces, Tetris ends.
