Dungeons & Dragons or D&D is a tabletop role-playing game. Players create fantasy characters and embark on a journey through a world built by the Dungeon Master, fighting monsters, completing quests, and interacting with all sorts of magic.
Players create characters, choose their class, species, and abilities, maneuver them through role-playing and combat, and work cooperatively with each other. The Dungeon Master often writes the setting, writes quests, referees the rules, and controls every monster and non-player-character the players interact with. Campaigns are often fluid, with the story changing depending on the actions the players decide to take.
