Just Dance 2021 offers a dance experience in which gamers mimic the movements of an on-screen dancer to a selected song using motion controllers or a dedicated smartphone app. This dynamic interaction creates a feeling of immersion and responsiveness in the process. Additional options are available, such as a gamepad and keyboard navigation.

The familiar user interface of its predecessors remains intact. Notable improvements include a revamped World Dance Floor, which hosts competitive tournaments in three separate rooms catering to different skill levels: Chill Panda, Fabulous Hippo and Fierce Deer for experts. A new results screen has been introduced, providing detailed statistics on dance performance accuracy, a feature exclusively available during a single session.

In addition, turning on Fast Play mode provides a smooth transition to dancing, eliminating the need to agonize over song selection. Just Dance 2021 retains the core mechanics that have made the series a favorite choice for dance lovers. With multiple modes and a revamped competitive platform, it offers a fun and accessible dance experience for gamers of all skill levels.
