Tetris Unblocked, Play Free Online Game for School at TOG

Tetris is a puzzle video game designed by Aleksey Pajitnov from June 1984 on Elektronika 60. Tetris Unblocked challenges the player to complete lines by moving pieces of different shapes, the tetrominoes, which scroll from the top to the bottom of the screen. Completed lines disappear while earning points and the player can refill the freed boxes. This old classic game has no end: the player loses the game when a tetromino is stuck at the top.

Tetris Online is mainly composed of a playing field where pieces of different shapes, called tetriminos, descend from the top of the screen. During this descent, the player can only move the pieces sideways and rotate them on themselves until they touch the bottom of the playing field or a piece already placed. The player cannot slow down or prevent the falling of coins, but in some versions can speed it up.

The goal for the player is to make as many lines as possible, in order to keep space to place future pieces. Once a line is completed, it disappears, and the blocks above drop by one row.

Tetris High Score Record

The player gets a score, which essentially depends on the number of lines made during the game.

According to the Record Setter:

Matthew Buco achieved the highest possible score of 999,999 points in Tetris(NES). He accomplished the feat with only 207 completed lines.

Game Over

If the player fails to remove the lines quickly enough, the screen can then fill up to the top. When a tetrimino crosses the field of play, and prevents the arrival of additional tetriminos, the game ends.

Tetris Endless Game

The game never ends with the player’s victory. Before losing, the player must try to complete as many lines as possible. To do this, it can eliminate several lines at once, earning it bonus points in most versions of the game. It is possible to complete up to 4 lines at the same time.
