Dance Dance Revolution, or DDR (known as Dancing Stage in Europe), is a music video game series produced by Konami. It was introduced to Japanese video arcades in 1998, after being shown at the Tokyo Game Show earlier that year. Since then, the game has gained significant popularity elsewhere in the world, including large portions of North America and Europe. As of 2005, over 90 official versions have been produced, including those for home video game consoles. The Dance Dance Revolution series is a subset of the larger Bemani series of music games.

The game is typically played on a dance pad with four arrow panels: up, down, left, and right. These panels are pressed using the player's feet, in response to arrows that appear on the screen in front of the player. The arrows are synchronized to the general rhythm or beat of a chosen song, and success is dependent on the player's ability to time his or her steps accordingly.
