unlockable. The song list includes seven songs from Dance Dance Revolution 3rdMix. Most of the new songs in 2ndMix (with the exception of "BAD GIRLS", "BOYS", "HERO", "stomp to my beat", and the So-REAL Mix of "MAKE IT BETTER") were included in the North American version of Dance Dance Revolution for the PlayStation. Dance Dance Revolution 3rdMix , sometimes abbreviated as 3rdMix, is the third game in the Dance Dance Revolution series of music video games. It was released in Japanese arcades by Konami on Saturday October 30, 1999. The arcade machine is the first to be based on Bemani System 573 Digital. It has a total of 72 songs, 35 of which are new to the arcade series. Instead of Easy, Medium, and Hard, the mode selection now offers "Soft", "Medium", and "Nonstop". Soft, a replacement of Easy, activates the Little option permanently and only allows one song to be selected. Medium leads to normal gameplay. Nonstop is a new mode in which players select a course which contains 4 songs back-to-back.

The game is the first to add Double Maniac/SSR stepcharts, but these are not available in 2ndMix Mode. The difficulty scale has been further increased to 9, labeled as "Catastrophic". The game still utilizes the jukebox-style song list but modifies it so that the highlighted song's CD is displayed to the front. Instead of being accessed through codes, players may choose a character through a dedicated screen. The game is the first to differentiate the colors of arrows based on their timing, an option known as "Vivid". Vivid is turned on by default in 3rdMix and 2ndMix Modes, but must be enabled with a code in SSR Mode, as "Flat" (all arrows are the same color;
