# What is Dominoes?

Dominoes are a game that is played by stacking individual pieces in long lines. When the first domino is tipped over, it causes the rest of the line to fall down. In a fun way, dominoes can be used to create complex designs.

Dominos, like playing cards, are a variant of dice. They are shaped like black and white rectangles and bear identifying marks on one side. The other side is blank or identically patterned. They are most commonly used for positional games.

Western dominoes were introduced in the mid-18th century and are generally considered to be an English adaptation of Chinese dominoes. Chinese dominoes are different from Western dominoes in that they have no blank faces and are intended for trick-taking games.

A number of variations on the classic “5s-and-3s” game exist, such as “7s-and-5s,” which is played by arranging a domino edge to edge against another in such a way that the two adjacent faces are either identical (e.g., a 7 to a 5) or form a specified total. Similarly, a “6s-and-3s” game has one domino for each possible combination of six spots on each end.

These types of games have a long history, dating back to the 10th century. In Chinese culture, they are called pupai. In Western culture, they are often referred to as “dominoes” or “playing cards.”

Dominoes have a strong connection to the concept of identity and self-image. The earliest versions of the game were played with Chinese dominoes that were designed to represent each possible face of two thrown dice.

The modern version of the game, known as ā5s-and-3sā or ā6s-and-3s,ā is usually played in pairs by two players. Each player in turn places a domino edge to edge against another. The players try to match the spot number on their domino to the face of the other domino.

Many people play dominoes as a form of entertainment. These games can be simple, such as a game of “tic-tac-toe,” or they can be complicated, such as a game where the aim is to move all the pieces in a particular sequence.

Some children prefer to play with dominoes in a more traditional way, by laying them out on the floor and knocking them down. Others use them in creative ways, such as to make 3-D structures and pictures.

There is a lot to learn from the process of building and toppling dominoes. Here are some tips:

#### 1. Design a theme

The next step is to plan the design for the installation. Hevesh decides on what type of arrangements she wants to include, such as grids that form pictures when the dominoes fall or stacked domino walls. She also considers how the dominoes will connect and what color combinations she will need.

#### 2. Calculate the number of dominoes

Hevesh then calculates how many dominoes of each color she will need to create her installation. This calculation helps her make sure that the dominoes are symmetrical and that they will work together smoothly.
