beatmania IIDX 4th style is the second home release in Konami's IIDX rhythm game series, featuring more than 50 tracks, primarily from the arcade version of the same title. As usual for the beatmania series, the player is given seven piano keys and a turntable, and must play along with the notes that scroll down the screen to play the music. There are three main modes: Arcade mode tasks the player with completing several tracks in succession, Free mode lets the player freely play any unlocked song, and Practice mode lets the player practice parts of songs without danger of failure.
