#### What is a Domino?

A domino is a small rectangular wood or plastic block, each half being blank or marked by dots resembling those on dice. It is used in a game played by placing one tile edge to edge against another in such a way that the numbers on the adjacent faces match (or “match up”). The game can be as simple or complex as desired, and it is often played with the goal of making a long chain of tiles whose ends show a certain number. A player may not play a tile that will result in both the end and the middle of the chain showing the same number, as this would defeat the purpose of the game.

Dominos are also a popular tool in classrooms to teach students addition and subtraction. When a student draws the dots on a domino, the teacher can call out a number and students will try to add or subtract as many of those numbers as possible. The teacher then writes the total on the board. This activity is usually done with a double-six set of dominoes, although it can be done with a double-twelve or even a double-nine set.

The word domino has been around in English for almost 400 years, and it has been a part of the vocabulary in several languages. The word is derived from the Latin domino, meaning “heavy” or “large.” In the early 18th century, it was used in several ways, including as a term of praise, but the most common use of the word is for the game itself. Dominos are now a part of most school playgrounds.

Hevesh is an expert in creating awe-inducing domino arrangements, and she’s worked on projects involving up to 300,000 dominoes. When she creates a new display, Hevesh spends months testing out each piece to make sure it will work properly. Her largest domino installations take several nail-biting minutes to fall, as they tumble according to the laws of physics.

While some people enjoy playing the games that can be created with dominoes, many are drawn to them for their artistic possibilities. Artists use the pieces to create straight lines, curved lines, grids that form pictures when they fall, stacked walls and even 3D structures like towers and pyramids. In recent years, the popularity of domino art has increased and many people have found it a rewarding hobby to pursue.

Dominos have also been used in art, including architecture and design. Some artists have used them to create geometric shapes, while others have made paintings and murals that are inspired by their shape or color. The domino motif has also been used to make political statements, as with a mural depicting the collapse of a building in the aftermath of the terrorist attacks in September 2001.
