Britney's Dance Beat for the Game Boy Advance is a rhythm game based on pop star Britney Spears.
The game's story mode allows players to dance along with Britney in two stages: Practice Mode and Concert Mode. In Practice Mode, players must complete a series of songs to unlock Concert Mode, which increases in difficulty. The gameplay involves a spinning radar-like object that highlights the buttons to press in rhythm with the music, while a video of Britney dances on screen.
The game's gameplay is centered around hitting notes in time with the music. Simple songs require only one button to be pressed, but later songs add additional buttons and require simultaneous D-pad input in Concert Mode. Players must reach a scoring threshold to complete a song and unlock pictures or videos of Britney. A two-player mode via link cable allows for competition, while Puzzle Mode features a simple sliding puzzle with four different pictures.
