Beatmania Append 3rdMix Mini is a smaller version of the PlayStation game Beatmania Append 3rdMix, it contains the same features as the main version but only five songs: find out, life goes on, Queen's Jamaica, tribe groove, and wild I/O.

The game came bundled with the soundtrack for the bBeatmania 3rdMix arcade game, titled Beatmania 3rdMix complete.

Since this is an Append release, it needs another Beatmania title to act as a key disc to boot the game.

The game is played with a controller with one turn table and 5 keys, three white and two black. On the screen you will see bars moving from the top to bottom in columns representing each of the keys and the turntable. When the bars reach the judgement line it is time to scratch.

Unlike the arcade counterpart, the PlayStation version does not have a combo counter. Expert mode is also missing from this version of the game.
