In economics and decision theory, a small-numbers game is a situation in an oligopolistic market in which the actions of one player have direct unforeseeable consequences for other players.
Economics is the social science that studies the production, distribution, and consumption of goods and services.
Decision theory is the study of the reasoning underlying an agent's choices. Decision theory can be broken into two branches: normative decision theory, which gives advice on how to make the best decisions given a set of uncertain beliefs and a set of values, and descriptive decision theory which analyzes how existing, possibly irrational agents actually make decisions.
A market is one of the many varieties of systems, institutions, procedures, social relations and infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services in exchange for money from buyers. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and resource allocation in a society. Markets allow any trade-able item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale.

Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one or more one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.
Badminton is a racquet sport played using racquets to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" and "doubles". Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the racquet and landing it within the opposing side's half of the court.
Association football, more commonly known as football or soccer, is a team sport played with a spherical ball between two teams of eleven players. It is played by 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field called a pitch with a goal at each end. The object of the game is to score by moving the ball beyond the goal line into the opposing goal.

The sport is known to be fast-paced and physical, with teams usually consisting of six players each: one goaltender, and five players who skate up and down the ice trying to take the puck and score a goal against the opposing team.
Kabaddi is a contact team sport. Played between two teams of seven players, the objective of the game is for a single player on offence, referred to as a "raider", to run into the opposing team's half of a court, tag out as many of their defenders as possible, and return to their own half of the court, all without being tackled by the defenders, and in a single breath. Points are scored for each player tagged by the raider, while the opposing team earns a point for stopping the raider. Players are taken out of the game if they are tagged or tackled, but can be "revived" for each point scored by their team from a tag or tackle.

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
Table tennis, also known as ping-pong, is a sport in which two or four players hit a lightweight ball back and forth across a table using small rackets. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: players must allow a ball played toward them to bounce one time on their side of the table, and must return it so that it bounces on the opposite side at least once. A point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage.
Volleyball is a popular team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules. It has been a part of the official program of the Summer Olympic Games since Tokyo 1964.

A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time, either locally or over the internet. During its early history, video games were often single-player-only activities, putting the player against preprogrammed challenges or AI-controlled opponents, which lack the flexibility of human thought. Multiplayer games allow players interaction with other individuals in partnership, competition or rivalry, providing them with social communication absent from single-player games. In multiplayer games, players may compete against one or more human contestants, work cooperatively with a human partner to achieve a common goal, supervise other players' activity, co-op. Multiplayer games typically require players to share the resources of a single game system or use networking technology to play together over a greater distance.
Forwards are the players on an association football team who play nearest to the opposing team's goal, and are therefore most responsible for scoring goals.
The NBA G League, or simply the G League, is the National Basketball Association's (NBA) official minor league basketball organization. The league was known as the National Basketball Development League (NBDL) from 2001 to 2005, and the NBA Development League from 2005 until 2017.

At the conclusion of the 2013–14 NBA season, 33% of NBA players had spent time in the NBA D-League, up from 23% in 2011.

The NBA draft is an annual event dating back to 1947 in which the teams from the National Basketball Association (NBA) can draft players who are eligible and wish to join the league. These are typically college basketball players, but international players are also eligible to be drafted. College players who have finished their four-year college eligibility are automatically eligible for selection, while the underclassmen have to declare their eligibility and give up their remaining college eligibility. International players who are at least 22 years old are automatically eligible for selection, while the players younger than 22 have to declare their eligibility. Players who are not automatically eligible but have declared their eligibility are often called "early-entrants" or "early-entry candidates". The draft usually takes place near the end of June, during the NBA offseason. Since 1989, the draft has consisted of two rounds; this is much shorter than the entry drafts of the other major professional sports leagues in the United States and Canada, all of which run at least seven rounds. Sixty players are selected in each draft. No player may sign with the NBA until he has been eligible for at least one draft.
