Dance Dance Revolution, more commonly known as DDR, is a music arcade game. It is also available at home on XBox, Playstation systems and PC, if you buy the home dance pads. The game involves choosing a level of difficulty (begginer, light, standard, heavy or challenge/oni) and you can play on single (one dance pad), doubles (two dances pads that you need to use simultaneuosly) or versus (2 people play the same song on different dance pads). You then choose a song. Each song has a sequence of arrows and the dance pads have 4 arrows (up, left, down, right) that you must step on as they come on the screen in beat to the music you choose.

It's an easy game to pick up but a hard game to master. As you raise your levels of difficulty there are more arrows per beat and it's harder to keep up with the arrows. It takes concentration and eye-foot coordination to pass songs. After every song you get a grade depending on how well you did. There are ratings as you play that tell you how well you were on beat. Perfect means you were exactly on beat, great means you were a little off, good means you just made it, almost speaks for itself, and miss means you totally missed the beat. The grades at the end range from E (failing) to AAA (getting ALL perfects, not one great is allowed). AA is greats and perfects. A is greats, perfects and goods. Anything lower (B, C, D) is a combination of all the rankings.

It's an addictive game, most people who play once get hooked easily, especially since the simple gameplay makes it good for any age group to play. The game is made by Komami and ranges from $0.50 to $1.50 at the arcades or anywhere from $60-$1000 for the home version depending on which dance pad and version you get. But no matter where you play the fun doesn't change.
