This article is about the game. For the geometric shape, see Tromino.
A game of Triominoes. Note how adjacent tiles are placed with matching corner values, and note the completed hexagon of six tiles (with corner values of 1 at the center). There are two uncompleted hexagons of five tiles, also with corner values of 1 at the center. One could be completed with the 1-1-3 tile, and the other cannot be completed, as the required tile would be 0-2-1, which does not exist.
Triominoes is a variant of dominoes using triangular tiles published in 1965. A popular version of this game is marketed as Tri-Ominos by the Pressman Toy Corp.[1]
