Just Dance 2017 is the 2017 edition in the main series of the Just Dance dancing games where players perform dance routines, mimicking the moves of on-screen performers, to earn points. It continues support for the control mechanism introduced in Just Dance 2016 and Just Dance Now where an app for Android and iOS phones turns the device into a controller for the game, registering movement through the accelerometer/gyroscope.
The game modes for this edition are Just Dance (with a Rival and Co-op mode), Just Dance Machine, World Dance Floor, Just Dance TV, Dance Quest, Sweat & Playlists, and Video Challenge. There is support for both local and online multiplayer. The main Just Dance mode introduces 40 new tracks to the game with artists such as Ariana Grande, Beyoncé, David Guetta, Justin Bieber, Queen, The Weeknd and so on with an average song length of about one minute.
Players pay for a subscription service called Just Dance Unlimited , which provides access to about 200 additional songs from a streaming library. This service is only available for the PS4, Wii U, Windows and Xbox One versions and includes both new tracks and songs from previous editions. Most of the PAL versions include a three-month subscription by default.
In the main Just Dance mode players go through the classic Rival mode or play as a team in the Co-op mode. Songs categories include Solo (one dancer), Duet (two dancers), Trio (three dancers), Quartet (four dancers), Just Dance 2017, Mashup and more. While playing, upcoming moves are shown in the bottom right corner while characters act them out.
Just Dance Machine is a new game mode where the player needs to help two aliens by providing dance energy so they can get back home. World Dance Floor is the online multiplayer mode to compete against other players in real-time. The score for each player during a song is shown through a ranking on the left side of the screen.
Just Dance TV returns to watch video clips of players around the world dancing to see their performances or to learn from them. Dance Quest also returns as a series of challenges organized around different themes and playing against the scores of AI opponents, as well as the fitness-like Sweat & Playlists mode to create custom workouts.
Another returning mode is the Video Challenge to compete against another player in an asynchronous way through a video tied to the dance routine. The game also captures the player's feed when a camera is available and at the end of the songs it can be shared as a new challenge for other players.
