A Tetrimino is a geometric shape composed of four connected squares, commonly used in the game of Tetris. Each Tetrimino can be rotated and placed in various positions on the game board, creating different patterns and lines. There are seven standard Tetrimino shapes, often referred to by letters: I, O, T, J, L, S, and Z. In Tetris, players aim to arrange Tetriminos to form complete horizontal lines, which then disappear, earning points. The game becomes progressively challenging as the Tetriminos fall faster, requiring quick thinking and strategic placement to avoid filling the board.
