DJMax (Korean: 디제이맥스, dijeimaegseu) is an action-rhythm video game series created by Neowiz MUCA.

Games feature mostly experimental music and visual art from Korean DJs, artists and composers.

The first game in the series, DJMax Online, started on June 13, 2004 (closed alpha test) as a web based service for the Windows platform.

Pentavision worked together with Korean company Gammac to manufacture a special DJ controller for the game which was then bundled together with the limited edition.

[3] Pentavision announced an arcade music game named DJMax Technika on December 31, 2008.

United States-based developer PM Studios officially announced on May 25, 2010 that DJMax Portable 3 would be released in North America.

[citation needed] Tap Sonic is a spin-off of the DJMax series for the iOS and Android mobile platforms by Neowiz Internet in partnership with Pentavision.

Hitting the correct notes fills in the missing instrument sounds from the melody and gives player points.

It speeds up the game and makes it harder to hit the correct notes but it also allows player to reach much higher Combo values.

After passing the Arcade mode, the player usually sees a small "Thanks for playing DJMAX" video clip.

The player uses the PSP's analog stick to move active track to be either left or right, default position being center.

These additional tracks only feature three lines so player only has to press the square, triangle and circle buttons while moving the analog stick correspondingly to hit the notes.

In this arcade series (which also has one entry for the PlayStation Vita and mobile platforms), players have to tap the screen at the moment when a moving slider crosses the symbols.

[5] Due to the comparable similarity between DJMAX games and the Beatmania series, including the interface and keysounding implementation, Pentavision received an intellectual property infringement filing from Konami on December 24, 2008.
