A game is a structured type of play that can be used for entertainment or as an educational tool. It is usually undertaken in a competitive context, such as sports or video games, although it may also be social (such as role-playing games and board games) or artistic (such as jigsaw puzzles).

The elements of a game are its tools, rules, and interaction. A game can require skill, strategy, luck, or a combination of all three, and it is classified according to those characteristics. A game can also be a physical activity, such as hide-and-seek or tag. In addition to its interactive components, a game requires an environment to exist in, which is what differentiates it from a toy or a book.

Generally, the environment defines how a game is played; for example, an auto race takes place in a race track or on a city street. The structure of a game can also be used to communicate its rules and structure, such as visual cues or audio announcements. An ancient Egyptian senet game board from 1390 to 1353 BC, for example, is engraved with rules for playing the game of dice.

Playing games provides a variety of benefits, including the development of social skills, critical thinking, and improvisation. The fast-paced action of many games requires quick responses, which teaches players to react to changing conditions. This can be applied to the workplace, as employees need to be able to think and act quickly when a work crisis arises.

Games can stimulate a player’s imagination and foster an interest in different cultures. They can also provide a way for children to learn about historical events and people, as many games are based on actual history and feature characters from other parts of the world. This is especially true of computer and video games that can immerse players in other cultures through the use of a foreign language or virtual environments.

Studies show that some games improve health by increasing physical activity and reducing anxiety and depression. In addition, some games can help with PTSD, or post-traumatic stress disorder, by keeping the brain busy and distracting it from negative flashbacks. Specifically, researchers have found that pattern-matching puzzle games can reduce the number of PTSD-related flashbacks by up to 50% in some patients.

Serious games are an emerging field in which interactive games are employed for professional and educational purposes. For example, Minecraft: Education Edition has been used to teach programming and history, and Medical Realities teaches medical students about anatomy using VR. Other applications of serious games include training programs that employ gaming principles to make the learning experience more engaging for employees and improve retention rates. For example, incorporating the instant feedback that is a core aspect of many games can encourage employee engagement and allow them to test their knowledge before moving on to more challenging tasks. This technique can also be useful in developing soft skills, such as teamwork.
