The karaoke gameplay is similar to other singing games such as SingStar and Karaoke Revolution. The game comes packaged with a USB microphone.[4] To score, the player must sing in time and in tune with the lyrics as they scroll at the bottom of the screen, with a musical staff to indicate the correct pitch and where the player's current pitch is. Rather than using phonetic detection, the game bases the score on how well the player matches the rhythm and pitch.
The dancing portion uses the Wii Remote and optionally the Nunchuk attachment. As the song plays, the player must move the remote left, right, down or up in time with the beat of the song to earn points. Like EA's SSX games, repeating the same movements will reduce the player's score, so the player must continually string together different orders of movements, as well as changing the dancing style.[5] A "boogie meter" fills with successful dance steps and strings of dance steps. While filled, the player can attempt a special dance move by holding down a button on the remote and then following the exact order of steps (4 to 6 steps long) that comes up. Successful execution of these steps in order and in time with the music will perform that move, while failure will detract some of the boogie meter. The player can move about the dance floor, picking up tokens, score multipliers, and boogie meter boosts when they appear. If the Nunchuk is used, the player will be given special solo sections where they can control the character's facial expression while a phrase of music goes by. Additionally, the user can enter a "Strike a Pose" mode, requiring them to tilt the Nunchunk to have the on-screen character point at an ever-decreasing set of targets for additional points. While the player can also use the basic dancing controls in karaoke mode, these do not affect the score there.
During the story mode, covering five chapters for each of the five characters in the game, the player can only advance after achieving a minimum score on the game. In regular play mode, their score is rated against pre-set scores for performances, and are rewarded with tokens for how good the performance was. Tokens can be used in the in-game store to unlock additional songs, stages, and outfits for character customization.
Players have the ability to create music videos of regular performances, which can include switching camera positions and adding screen effects.
Boogie features competitive and co-operative local multiplayer modes.
It was announced by EA on July 10, 2007 that there are 39 confirmed songs.[6] All songs are covers of the original tracks.
