A domino is a small rectangular block of wood or plastic, each side bearing dots that resemble those on dice. The word is also used for a game played with such blocks, usually by two or more players. The game involves placing a domino on the table, and then pushing it over so that its ends touch other pieces and cause them to fall in turn. The first player to complete the chain wins.
The term domino can also be used as a metaphor for any action that leads to a cascade of consequences. For example, someone might say that a particular politician’s decision to cut benefits for veterans will lead to a domino effect in which other politicians follow suit. Another example is a business decision that has unexpected consequences. For instance, when Domino’s CEO replaced the previous leadership in 2004, the company was already $943 million in debt and losing market share. It was clear that something needed to change quickly if the company wanted to survive.
When domino artist Hevesh creates her mind-blowing creations, she follows a version of the engineering-design process. She begins by considering the theme or purpose of an installation, then brainstorms images or words to use in her design. Next, she considers how many dominoes she’ll need to accomplish her goal and calculates the arrows for a line that will lead to the desired outcome. She then sketches the layout of her track on paper, making sure to include an arrow for each domino that needs to be pushed over.
Once she’s happy with her design, Hevesh starts assembling the dominoes on the board. Depending on the complexity of her design, she may need to glue or tape the dominoes in place. She also uses markers to mark where she wants each piece to go and draw a line that shows the direction in which the dominoes will fall.
There are a number of different games that can be played with dominoes, including blocking and scoring. In addition to these, there are also solitaire and trick-taking games, which were once popular in some areas because they allowed people to play cards when religious proscriptions made it illegal to do so.
A basic domino set consists of 22 tiles, which can be arranged in multiple ways to form a chain. Most games are played with two to four players, and each player takes turns playing a domino onto the table. If a player plays a tile with a number showing on only one end, it will need to be “stitched up” to match a tile that has a number showing on both ends.
In the past, dominoes were made from materials such as silver lip ocean pearl oyster shell (mother of pearl), ivory, and dark hardwoods like ebony. These sets tend to be more expensive than polymer versions, but offer a unique aesthetic and a heavier weight. More recently, dominoes have been made from more unusual natural materials such as stone (including marble, granite, and soapstone); metals; ceramic clay; and even frosted glass or crystal.
