A game is an activity with a specific goal, rules and interaction. It may be competitive or not, and it can take a variety of forms. Games include sports, board games and video games. They can be played alone or with a group, by amateurs or professionals; and with an audience of non-players (such as spectators at a sport event). The game may also have a purpose beyond entertainment or competition, such as training, exercise, or social interaction.

In the context of video gaming, it can refer to a single-player or multiplayer game that is run by a computer program. The goal of these games is to complete the game by following a set of rules and objectives in a virtual world. Video games can be categorized by genre, such as action, shooters, strategy, role-playing, fighting or racing. Some games can be complex, while others are more simple and straightforward.

The term game has many synonyms, including fun, jest, sport, play, and toy. Fun generally implies humor or gaiety, while jest hints at lack of seriousness or ulterior motive. Sport often implies competitiveness, whereas play stresses lack of earnestness or malice.

Many people enjoy playing games, whether it is an arcade or video game, or a card or board game. It is often seen as a form of recreation and relaxation, rather than work or study. It is considered to be healthy for young people, and can teach the player how to deal with risk and uncertainty. It can also be used to improve cognitive and motor skills.

While the gamer stereotype of the lonely, isolated video gamer persists, research suggests that this is not the case for most gamers. In fact, more than 70 percent of gamers play with a friend. Multiplayer video games are particularly social and have helped to create real-world communities. Moreover, gamers who play violent video games tend to be more helpful to others while playing, a recent study showed.

Some of the most popular video games are the ones that allow players to control a virtual character, such as a person, car or animal, in a fictional setting. These games are typically more immersive than their predecessors, which were often based on straight action. Modern video games often have a storyline that the player follows, and they can have multiple levels with different obstacles to overcome.

Another type of video game is one that simulates a particular sport, such as football, basketball, hockey, golf or tennis. These games usually have more realistic graphics than their simpler counterparts and can be played either with a physical controller or an electronic device. They can be both single-player and multiplayer, and some have a career mode where the player controls their own team. There are also some that focus on the gameplay and are not based on any actual sports. The most popular sport simulation games are PES, FIFA and Virtua Tennis. These games are often very challenging and require a lot of practice to master.
