Domino is a game of chance, skill and planning that can be played by two or more players. It is usually played on a flat surface, such as a table. There are many different games that can be played with dominoes, and each game has specific rules. Some of these games use straight lines, while others include curved lines that form pictures when they fall or are stacked to make 3D structures like towers and pyramids.
When playing a domino game, each player places a domino tile on the table, positioning it so that one of its ends matches an end of another domino. Then, as each player plays a tile, the chain of matching ends grows in length. When a domino chain has been completed, the winning players are those who have the most matching pairs of tiles.
Some games of domino are block-and-draw games, in which the players try to build a line that connects all of the matching ends. Other games require players to make a number match the total amount of dots on a domino or another piece that has already been played.
In the United States, there are two basic types of domino sets: double-twelve and double-nine. The 91 and 55 tiles in these sets, respectively, allow four to eight players to play at the same time.
Each domino has an identity-bearing face and a blank or identically patterned face. The identifying face is marked with an arrangement of spots, called pips, that resemble the numbers on a die. The blank face is usually white, but some dominoes are made of other colors.
The most basic domino set consists of 28 pieces. These can be used for a variety of simple, positional games for two to four players. Each domino is made of small rectangular blocks, each bearing a pattern of dots or numerals on one side and a blank or matching-pattern face on the other. Some of the most common games are variants of solitaire or trick-taking card games. These types of games were once popular in some areas to circumvent religious prohibitions against playing cards.
In these games, each player takes turns placing a domino on the table. Then, each player attempts to match a tile that has already been placed by placing a new domino so that its one of its matching ends touches the adjacent end of the existing domino. The winner is the first player to complete a domino in this way.
Dominos are easy to set up and can be played with just a few pieces. Whether you’re setting up dominos on the floor or on a table, they will stand upright when you barely touch them with your finger. As you move your finger, however, the dominoes will tumble over. This phenomenon is caused by the fact that gravity, which exerts a downward force on the standing domino, causes energy to be converted from potential to kinetic, producing the chain reaction that causes domino after domino to fall.
