How to play Tetris (unblocked)

Tetris players complete lines by moving different shaped pieces (tetrominoes), which descend on the playing field. The completed lines disappear, and the player gets points for filling the vacated spaces. If the playing field is filled, the game is over. A player's score will rise the longer they delay the inevitable outcome.

The players in multiplayer games must last longer than their opponents, and in certain versions, the players can inflict penalties on their opponents by completing a significant number of lines. Different adaptations have added variations to the game's theme, such as three-dimensional displays or a system for reserving pieces.

Tetriminos are the pieces on which Tetris is based. The original Electronica 60 version of Pajitnov's Tetris used green brackets to represent blocks. Tetris on the Game Boy/Game Boy Color and most dedicated handheld games use monochrome graphics, but most popular versions use a separate color for each distinct shape. Before Tetris Company's standardization in the early 2000s, the colors varied greatly from implementation to implementation.
