Dance Dance Revolution Solo 4thMix and Dance Dance Revolution Solo 4thMix Plus were released concurrently with 4thMix and 4thMix Plus respectively, designed for use with Solo cabinets. The changes in the actual game engine are few, but significant. The 4 and 6-panel modes are offered instead of the usual options, and the chubby arrows of the Solo series also appear. Multi-player Mode from the Solo series is not present in either game.
An ALL MUSIC MODE feature is included for Dance Dance Revolution 4thMix Plus where players have access to all songs in the game instead of picking music genres.
