A tetromino is a geometric shape composed of four squares, connected orthogonally (i.e. at the edges and not the corners). [1] [2] Tetrominoes, like dominoes and pentominoes, are a particular type of polyomino. The corresponding polycube, called a tetracube, is a geometric shape composed of four cubes connected orthogonally.

Apr 12, 2025 · A tetromino is a 4-polyomino. There are five free tetrominoes, seven one-sided tetrominoes, and 19 fixed tetrominoes. The free tetrominoes are known as the T-tetromino, L-tetromino, skew tetromino, square tetromino, and straight tetromino, respectively.

A tetromino is a shape made up of four squares directly connected to each other by their edges. [ 1 ] [ 2 ] If one considers a tetromino that has been moved (translated), turned (rotated) or flipped (reflected) to be the same shape, there are five distinct tetrominoes.

Slide, rotate, and flip the five tetromino pieces to fill in the puzzle. Try all five puzzles!

Each shape consists of 4 squares, connected along their edges (not just at the corners):

Not to be confused with Tetris, this tool provides endless opportunities for learning and playing. The word “Tetromino” combines the words “domino” and “Tetra,” which means four. In each shape, there are four squares, arranged in different ways. Here’s how to play tetromino. Simply drag and drop shapes onto the board.

Tetromino: Two-dimensional figures made of four connected congruent squares. Tiling: Fitting individual tiles together with no gaps or overlaps to fill a flat space like a ceiling, wall, or floor. Translation: A movement of a figure to a new position without turning or flipping it.

Tetrominos, occasionally known alternately as T etrads, B locks, Tetriminos (official name), or tetriminoes, are the blocks used in every known Tetris game. They come in seven shapes, all of which can be rotated and then dropped. Tetrominoes all have an area of four squares. In certain Tetris games, the colors of them vary.

The Tetromino is any shape constructed using four squares arranged orthogonally. There are only five possible permutations, called the "Free tetrominoes." The Tetrominoes feature prominently in many video games, starting in Tetris, where they are actually called Tetriminoes.

LITS is a logic puzzle with simple rules and challenging solutions. - 2 tetrominoes of matching types cannot touch each other horizontally or vertically. Rotations and reflections count as matching. - The shaded cells should form a single connected area. - 2x2 shaded areas are not allowed. * Tetromino is a shape made of 4 connected cells.
