Premium Play Darkness is a simulation game similar in concept to Artificial Academy games. The game has various sets, which includes locations such as classrooms, parks, a swimming pool, a red-light district, etc. The character editor allows customization of a 3D model with facial and body features, allowing the player to choose even the voice of the character between six voices. After using twice the H-mode the player can choose the four female main characters and other female sub-characters with character of his or her own creation and even choose their personality. The plot is divided in nine routes in total, and each of the routes you get are determined by the personalities you pick for the first two or three female main characters. There is no physical navigation in the game instead, the player will only see the story scenes and play the sex scenes that are between a story scene and another.

The H-Mode is split up between the Normal and the Hard mode. The player can then assume the role of either male, zombies or even monsters (both of them only on the Hard Mode), and begin sexual intercourse with an edited character. Unlike other Illusion games where there used to be some kind of performance meter, H-Mode in Premium Play Dark is purely aesthetic and nothing can be achieved from trying to perform well in a scene.
