Just Dance 4

The gameplay remains similar to other previous Just Dance games, as players are judged on their ability to mimic on-screen dancers performing a routine to a chosen song. Karaoke-styled lyrics have been revamped, with lyrics being highlighted in a pre-set color. New features in Just Dance 4 include dance battle routines, which allows up to two teams of two to fight as one of the two dancers from two previous songs, expansions to the game's Just Sweat mode, unlockable alternate routines for songs, and a "Puppet Master" mode exclusive to the Wii U version, which allows a player to use the Wii U GamePad to serve as a "Master" to manipulate the routine and visuals, allowing them to create their own mashups by choosing any of the four dance moves from all four entries in the Just Dance series, as well as the ability to use the "Strike A Pose" mechanic, in which players will have to match the pose shown on the screen, while the "Master" has to choose which player earn a bonus of 1,000 points or decides not to award the bonus points. Additionally, the Wii U Gamepad can also be used to draw during gameplay, as well as the option to display the lyrics on the Gamepad, and choose the next song while the current song is in progress. Previous additional modes (Simon Says Mode, Playlists, Medley, Speed-Shuffle, and Just Create (Xbox 360 only)) have been dropped. Additionally, the "On Fire" motive (from mostly Goods and Perfects in a row) and effort ratings have been removed, leaving only difficulty ratings and the "Gold Move" motive, which has been dropped in Mashups. The outfits and hairstyles of the dancers are now colored in a realistic style, rather than just solid colors. Players have "Dance Quests", six missions for each song, that can be completed. Each quest nets the player Mojo points. Downloadable songs do not have dance quests. Players can also create "Dancer Cards", which can display their favorite songs, best scores, challenges, and more. Personal leaderboards are also available for the Wii version of the game.

The game features 50 songs. Note: Several songs, including "Sexy and I Know It" by LMFAO, "Respect" by Aretha Franklin, "Weapon of Choice" by Fatboy Slim featuring Bootsy Collins, "Move Your Body" by Beyoncé, & "So Good" by B.o.B were planned to be featured in the game, but were ultimately scrapped for unknown reasons.

DLC's for Wii were available from October 18, 2012, until the closure of the Wii Shop Channel on January 30, 2019.

DLC's for Xbox 360 were also available on the Xbox Live Marketplace until its discontinuation on July 29, 2024.

DLC's for PS3 are region locked (e.g., DLC's bought from US PSN Store will not work on a Region 3 disc).

DLC's on Wii U were only available in the Nintendo eShop until its closure on March 27, 2023. Note: "You Make Me Feel..." is only available as DLC if it has not already been unlocked with a Cheetos code of the exclusive, which had a minor adjustment between the two versions, as the Cheetos mascot, Chester Cheetah, was shown on the Cheetos version, and not on the DLC version.
