Domino is a tile-based game, originating in Europe. It is played with a set of shuffled dominoes and a table. The rules vary from country to country, but are generally similar. The object of a game is to score points by attaching tiles from your hand to either end of already played dominoes. In some countries, a “5s-and-3s” scoring variant is used, in which the objective is to attach five or more dominoes so that each of them is divisible by five or three.
In the Western game, each tile is a member of a suit: threes and blanks are the military suits; jacks and queens the civilian ones; and sevens and eights are the combination of both. Most European sets do not include the military-civilian suit distinctions.
When a tile is placed on the table, it must be matched to another tile that has the same number. This can be done by laying the two tiles side-by-side, if there is enough space on the table, or by placing one tile adjacent to the other. The tile with the higher total number of pips wins, although in practice, this is not always the case, particularly when playing with many players.
The first player (determined by drawing lots or by the player holding the heaviest hand) places the first domino on the table, and the game continues until either one of the players has knocked the entire table over, or the last domino is played and the game ends. When this happens, the players are each awarded the number of dominoes they had in their hand at the start of the game.
There are several kinds of games that use dominoes, but the most common is “block and draw.” Each player draws a certain number of tiles from the stock. These tiles are usually arranged on the edge of the table, so that players can only see their own tiles, but not the tiles in the other players’ hands.
This makes it easier for the player to know how many he has remaining, and gives other players an idea of what they should expect to have at any time during the game. Most players in block-and-draw games play a single tile, but some play up to four or more.
A player can also lay down a single domino, or a line of dominoes, with a blank side. However, if the blank side of any of the other dominoes is touched, the two tiles can no longer be matched together.
Using the domino effect as a mental model to plan for success
A key part of the success of any business is to focus on the right things at the right time. Whether you’re creating an app for the new mobile platform or trying to convince your board of directors to approve the new merger, you’ll need to make a series of decisions and take action. The best way to accomplish this is to build a strong foundation, which starts with the right people, and then work on the most important tasks that need to be completed.
