Itetromino

Itetromino refers to a shape composed of four equal squares connected edge-to-edge. It is one of the five free tetrominoes, meaning it can be rotated and reflected. The Itetromino is characterized by its straight, linear arrangement of the four squares. When depicted in a grid, it typically resembles the letter 'I'. It is also known by various other names depending on the context, such as the straight tetromino or the line tetromino. In popular culture, Itetrominoes are famously featured in the tile-matching video game Tetris, where they are one of the seven distinct pieces. These pieces fall from the top of the screen and must be rotated and moved to form complete horizontal lines, which then disappear. The Itetromino is crucial in Tetris gameplay due to its ability to clear an entire line by itself and its distinctive vertical or horizontal orientation. Its geometric simplicity and common usage in puzzles and games make it a recognizable polyomino.
