Domino’s is a great example of a business that was struggling but managed to stay afloat thanks to leadership that listened to their customers and employees. This allowed them to make changes that benefited everyone. This includes relaxing the dress code and implementing new leadership training programs. These things were not easy to do but were vital in keeping Domino’s alive.

The word “domino” means something that sets in motion a series of events. It is also used to describe a chain reaction, such as one that occurs when someone drops a marble onto a piece of wood. In a game, dominos are set up in long rows and then knocked down by the players in turn. In the most common form of the game, each player begins with twenty-seven dominoes. Each domino features a square center and a line that divides it visually into two equal parts, each bearing from zero to six dots or numbers (called “pips”).

There are many games that can be played with dominoes, both positional and scoring, although a greater number of them involve special tiles called “wild” or “non-pips.” These have no marks on their faces but may be colored instead.

In positional games, each player places a domino edge to edge against another such that the adjacent faces match either in total or in some specified value; for example, matching a 6 to 6 with an 8 to 8. The remaining unmatched ones are called “sleeping” dominoes and remain the property of the owner of those pieces. If a player cannot play his or her last tile, the player passes the turn to the opponent. Normally, the player must choose from the sleeping dominoes, which are those that have not been played yet.

A domino is a polyomino of order 2, which means that it can be reconstructed from its face by alternating rotations and reflections. The number of polyominoes that can be formed from a domino is limited only by the available space on the table.

Dominoes are also used in mathematics to represent polygons, tessellations and other structures in the plane. In particular, a domino is useful for representing the plane in a rectangular coordinate system because the diagonals are straight lines and not the curved edges of a square or a circle.

In addition to domino games, dominoes can be used for educational purposes and to illustrate concepts such as angles, distances, patterns and proportions. A series of dominoes can also be set up on the floor to show a progression of geometric figures such as a triangle, hexagon or trapezoid. Dominoes are a popular toy for children and are often used in classrooms to teach counting, addition and subtraction. They are also often used in shows featuring a builder who creates complex and imaginative domino reactions for a live audience of fans. Some toy companies offer a wide variety of different domino sets. Others specialize in custom-made sets to be used for various kinds of domino games.
