Beatmania IIDX 6th style: new songs collection is one of the many titles in Konami's IIDX rhythm game series, featuring more than 60 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. The Beginner's and Drill modes introduced in 5th style also return. This edition also introduces a gallery mode where illustrations and the in-game videos can be viewed.
