Dance

Dance is one of the game modes of StepMania. It simulates the Dance Dance Revolution (DDR) game, and is the most widely played game mode.

Single (dance-single)
The typical mode of DDR that mostly everyone is used to, containing four panels: left, down, up, and right. Probably the most played and stepped for game mode.

Versus (dance-versus)
Two player mode where each person chooses a selected difficulty and plays with four panels.

Double (dance-double)
In this game mode, one player uses all eight panels on both pads.

Couple (dance-couple)
Two player mode with different patterns for each player and the playfields joined. Not widely played now due to its appearance being the same as double.

Solo (dance-solo)
One player mode with two extra panels added (top left and right diagonals) creating a six panel mode. This mode originated with the DDR Solo series, but is nowadays used to step keyboard files.

3 Panels (dance-threepanel)
SM5 only. This mode originated in DDR Solo 2000, where the arrows would be top diagonals and the down arrow. But for some reason, starting from SM5 alpha 1, the arrows got changed to left and right, which was fixed in SM 5.2 (formerly 5.1 alphas). Basically just single mode without the up arrow. Very very few charts have been stepped for this mode due to this mode being hidden in the main theme and not many people playing it.
