A domino is a mathematical polygon, or a line of equal-sized squares connected edge-to-edge. The word is also used to refer to the game in which players place tiles on a table and then knock over those tiles with the slightest touch. When a domino is knocked over, it creates a chain reaction that affects every other tile in the same way. This process is known as the Domino effect.

Domino is a game that requires strategic thinking and fast action. It can be played with a single player or multiple players. The rules of the game vary slightly depending on the type of play. In general, the goal is to score points by completing a set of dominoes, or by knocking out your opponent’s entire set.

One of the most common ways to use a domino is to place it so that it slides across the end of a line of adjacent dominoes and causes those dominoes to fall over, creating a chain reaction. This is often referred to as a “train” or a “snake line.”

Hevesh, who uses her skill in creative ways for fun and profit, follows a version of the engineering-design process when she creates a mind-blowing domino setup. She tests each piece of an installation to make sure it works correctly. Then she builds the dominoes into their final form, starting with the biggest 3-D sections. She then adds flat arrangements and finally lines of dominoes that connect all the pieces together.

To begin a game of domino, a player places a single tile on the bottom of the table and then raps it with his or her hand. Each domino features a different number of spots and belongs to a suit of that number. The most popular sets of dominoes feature the suits of double six and double nine. Players may also purchase “extended” sets, which allow them to build longer chains.

A domino that reaches its tipping point loses its potential energy and falls over. As it does, much of that energy converts to kinetic energy. Some of this energy is transferred to the next domino in the chain, which gives it the push it needs to fall over too. This continues with each new domino, until the last domino is pushed over.

In real life, Domino’s pizza CEO Don Meij exemplifies the Domino effect when he visits restaurants to see what employees are doing and how they respond. He has seen firsthand that the company isn’t meeting its customer expectations. Meij’s actions were a clear signal that something needed to change. His efforts were like a domino rally that addressed the issues that customers were complaining about. This helped the company improve its service and increase its market share.
