Domino is a game in which players arrange dominoes in long rows and then knock them over. It is also a metaphor for something that spreads and influences events in an uncontrollable way, such as an epidemic or a financial meltdown. The word is derived from the Latin dominus, meaning “lord” or “master,” and it has since become associated with cause and effect.
Dominoes are rectangular pieces of a material such as wood, bone or metal that have an arrangement of dots on one face and a blank or identically patterned side. These spots are called pips, and they are used to identify each domino. Some dominoes have no pips at all, while others have as many as 24 or more.
A typical domino set has 28 tiles. However, larger sets are often used for games that involve more than four players. These extended sets introduce more pips on each end of the tiles, making it possible to make more combinations of ends. Some examples of extended sets include double-nine (55 tiles), double-12 (91 tiles) and double-15 (193 tiles).
Although many different games can be played with dominoes, the most popular are the Block and Draw games. Typically, four players play these games with a standard double-six set of dominoes. However, the games can be played with any size domino set, even a double-nine or double-twelve set.
When a player places a domino on the table, it must be able to touch every other domino on the table. If it cannot, the domino is capped or “fenced,” and play passes to the next player. In most cases, the first player to place all of their tiles on the table wins.
Creating domino art requires careful planning and calculations. Whether the art is a line of dominoes that form a shape, a grid that forms pictures when they fall or a 3-D structure like a tower or pyramid, the artist needs to know how many dominoes are needed and what theme or purpose they are going to be used for before they begin designing.
A good way to practice this skill is to create a domino art on paper before trying it out with real dominoes. Write a domino track and carefully plan out the pieces you would need to complete it. You can also use a program such as Domino Designer to help you create your design and calculate how many dominoes are needed for it.
When a domino falls, most of its potential energy converts to kinetic energy, the energy of motion. This energy then moves onto the next domino, giving it a push that causes it to fall over. This process continues on as each domino impacts the next, causing the chain reaction to continue until all of the dominoes have fallen.
