Auditorium offers an innovative music-based puzzle experience for Mac users, where players engage in guiding streams of light particles to create melodic soundscapes. The core gameplay involves manipulating colored particles to fill various audio containers that correspond to different musical instruments. Successfully completing these tasks unlocks layers of music, providing an enriching auditory backdrop that evolves as players progress through the game.

The game is structured with multiple levels, each introducing distinct challenges that require strategic thinking and skillful manipulation of light streams. Players can change the color of the streams by navigating them through specific areas, ensuring they match the colors of the audio containers. The ultimate goal is to fill all containers at once, culminating in a complete soundtrack for the level, making Auditorium a unique blend of puzzle-solving and musical creativity.
