A game is a competitive activity that involves skill, chance, endurance, and social interaction, usually among two or more players. The object of the game is usually to entertain and educate the participants, and many games are played for social purposes. Games are a part of human experience across cultures and generations. They can be played by individuals or as a group, and are a great source of enjoyment and relaxation for those who participate.

While the purpose of a game may be to entertain, they have many other benefits, too. They are a form of entertainment that involves social interaction, which separates them from other forms of entertainment. For example, games can be fun and interactive, allowing the players to take the actions and emotions of the game world into the real world.

A game has rules and tools, which help players reach the goal. There are some games that require more skill and strategy, while others are more luck-based. Some games may include meta-rules that are immutable. These rules govern time-keeping, the rights and responsibilities of the players, and the boundaries of the game. The rules also help determine the goals of each player.

The most famous example of game theory is the Prisoner’s Dilemma. This game involves two criminals who are both being tried for a crime. The two have to choose between two different ways to communicate with each other. They are given four options: one of them involves paying the other’s crime, and the other offers them a higher reward for their confession.
