Domino is a small, flat rectangular block used in games to form lines of tiles with identical pips on each end or with a particular pattern of dots. These pips (or spots) indicate the value of the domino; for example, a double-six is valued highest, while a double-blank is the lowest. Dominos may be made from polymers, such as plastic or bakelite; they are also often carved in wood, silver lip ocean pearl oyster shell, bone, ivory, or ebony, with contrasting black or white pips.

Dominoes are usually arranged on-edge before the players; this allows each player to see his own tile and the number of other players’ tiles. When play begins, the first player draws his tiles and places them on-edge in front of him, typically in a line with a space between each set of tiles to prevent cheating. He then determines the value of each of his own tiles based on the number of matching pips, and begins to place his dominoes on the table, starting with the first tile in his hand, which is typically a double-six.

The dominos then begin to fall, one after the other, building up the chain until all of the players have played their tiles and the chains are complete. The winner is the first player to reach a point where all of his own dominoes are covered with numbers. Domino games are popular for all ages and can be used in schools to teach counting, addition, and subtraction.

Many people enjoy playing dominoes as a way to relax and pass the time, whether with friends or alone. Some people even make a career out of it, like 20-year-old Lily Hevesh, who has more than 2 million YouTube subscribers who watch her create spectacular domino setups in straight and curved lines.

Another company that has successfully employed the Domino’s business model is Domino’s Pizza, a national restaurant chain that offers delivery and pickup service. The chain’s success stems from its ability to stay on the cutting edge of technology, offering customers new ways to order their food. For example, Domino’s customers can now place orders by texting an emoji or using devices such as Amazon Echo.

A lesson that can be learned from Domino’s is to listen to your employees and customers. The chain’s top executive, Brandon Doyle, prioritized employee feedback and implemented a series of changes, such as a more relaxed dress code and leadership training programs. It also paid close attention to customer complaints and addressed them quickly and directly. This approach was successful and helped Domino’s earn a spot on the Detroit Free Press Top Workplaces list in 2016.
