You found Tetrobot!


The game Tetris - a word-mix of "tetra" and "tennis", is created in 1984 by the Russian game designer Alexey Pajitnov. In the original version of the game, the player must drop tetrominoes (four-element polyominoes) on top of each other, trying to create lines in a given grid. Once a line is created, the blocks in it get discarded. During the years, some of these discarded blocks managed to combine together and form the highly advanced robot Tetrobot. Tetrobot is known to speak only in binary and to know all infinitely many digits of the number Pi.
