Domino is a game in which players place tiles side by side. Each tile has a number of pips on one half and a blank side, or “blanks.” The player who lays the first tile is said to start the game. The player then takes turns placing tiles in a line (either straight or curved), aiming to match each tile with another by the pips on their ends and using the blank sides of the other tiles. When a domino has both the same color and pattern as the tile it matches, this is referred to as a double.

When a domino is flipped ever-so-slightly, it can knock over the entire line, and in the process, cause even more dominoes to fall over, creating a chain reaction. This domino effect is used in many ways, including metaphorically to describe a series of causal links within complex systems such as global finance or politics. It is also used in the mechanical sense, describing a series of dominoes that actually collide with each other, such as those used in Rube Goldberg machines.

For example, when someone says they have a domino effect in a job interview, they are referring to their ability to take one action that can affect several other actions. This domino effect is especially important in business, where the ability to influence a large number of people can result in major changes.

To succeed in a job, a person must be able to predict how others will react to the action and respond accordingly. For example, if a manager is aware that employees are dissatisfied with the quality of food, they can ensure the quality improves by taking steps to address the issue. In the case of Domino’s pizza, the company was able to successfully implement its new delivery system because it understood customer pain points and knew what they needed to do to satisfy those needs.

Domino can be played by two or more players, and the object is to make lines of dominoes of all colors on a flat surface, such as a table or the floor. The first person to complete a full row wins. In addition, a player may earn bonus points for completing certain types of patterns or combinations, such as a six-six-five.

There are many different games and variations of the game. Some involve blocking or scoring, while others require the use of strategy. The game is also popular as a way to practice counting and addition. In addition to being made of polymer, dominoes are also available in sets carved from wood, stone, ivory, bone or other materials. Some sets are designed to be historically accurate, with a design and style reflecting the period in which they were first made. For example, in the mid-18th century, dominoes were often crafted from ivory or a dark hardwood such as ebony with black or white pips. Other sets may be designed to have a more modern look, such as those crafted from ceramic clay or even frosted glass.
