triomino
Three-sided tile game
A triomino is a flat game piece made of three squares joined edge to edge, used in tile-matching puzzles and games similar to dominoes.
The pieces come in two shapes: a straight line of three squares or an L-shaped arrangement.
Players typically match numbered or colored sections when placing pieces on a board.
The name blends "tri" (three) with "domino," following the pattern of other polyomino games.
