Domino is a family of game pieces with matching pips that may be stacked end to end in long lines. When the first domino in a line is tipped over, it triggers the same effect on each of the other dominoes that follow. In this way, very elaborate–and sometimes chaotic–designs can be constructed and the number of possible outcomes is almost limitless. There are two major categories of domino games: blocking games and scoring games.

The markings on a domino, called pips, originally represented the results of throwing two six-sided dice. Each domino has half of the pips from one die and all of the pips from the other. The pips are often color-coded to differentiate different suits. The most common commercially available domino sets are double six and double nine, although much larger sets exist for players interested in a greater variety of game possibilities.

Each domino can be used as a playing piece in a variety of positional games that require skill, strategy and planning. In most of these games, a player places one domino edge to edge against another so that their exposed ends match: one’s touch ones, two’s touch two’s, etc. If all the ends are identical, a player is awarded points. Other games are based on number recognition, with the player attempting to place a single tile in such a way that it will cause a specific number of additional tiles to be played in order to complete the game.

In addition to purely recreational use, domino can also be used to practice math and social skills. Especially in classrooms, children can use domino to learn basic numbering and addition through the process of counting pips on adjacent tiles. Children can also develop hand-eye coordination by aiming to place dominoes in strategic spots on the board as they work together to build a chain of dominoes.

Many people enjoy using dominoes to create works of art, such as curved lines, grids that form pictures when the pieces fall and even 3D structures like towers and pyramids. Professional domino artist Hevesh has a YouTube channel in which she shows how to design and construct these structures.

While Domino’s pizza is famous worldwide, the company actually got its start by selling dominoes to local businesses. Founder Tom Monaghan realized that his customers had been asking for delivery and that the service would be a great way to boost profits.

Domino’s is a leading company in its field and offers a wide range of products to consumers, including pizzas, appetizers, pastas and cakes. The company’s marketing strategy is centered on its slogan, “think global, act local,” and it promotes itself through a variety of media outlets. The company has also developed and implemented a number of strategies to encourage its employees to be successful and keep up with customer demand.
