If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
The object of the game is to match the dancing moves at the right time to accumulate points. You'll see combinations of moves represented by the ARROW keys. Pull moves by copying the combination of arrows that come up on the screen. The more perfect you copy the moves, the more points you will get. Dance On!
Use Arrow keys to dance.
