The Circle Dance Floor 2010 is a furniture item granted when the player reaches level 172. When 2 or more players stand on the dance floor, the lights turn on and start flashing.
Before the levels were extended from 200 to 500 in March 2016, this item was one of the random items that came out of a Diamond Mystery Box rewarded from level 51 to 150. Because of that, there are Circle Dance Floors 2010 that can be traded and gifted.
