Volume Deal is a downloadable microgame in WarioWare: D.I.Y. and WarioWare: D.I.Y. Showcase. It was released on November 11, 2009 in Japan, October 11, 2010 in North America, and November 12, 2010 in Europe.
At the start of the game, someone is listening to music too loudly on a subway car. The goal is to have the superhero lower the volume, but not too much. If the player taps too many times, they have a chance to fix it before the microgame ends.
