The word "tetra" relates to the game Tetris because it is part of the name of the game. The prefix "tetra-" comes from the Greek word meaning "four," and Tetris is a puzzle game where players arrange falling blocks made up of four squares to create lines and clear the board. This connection is evident in the title of the game itself, which combines "tetra-" with "tennis," the favorite sport of the game's creator, Alexey Pajitnov. Additionally, the four-block shape is a key element of the game's gameplay mechanics and strategy, further emphasizing the significance of the term "tetra" in relation to Tetris.
