is a Japanese
visual novel developed by
Navel. It was originally released as an
adult game for
Microsoft Windows on January 30, 2004. It was subsequently followed by an all-ages release for the
PlayStation 2 (PS2) and an expanded adult release for Windows. The Windows version was localized in English by
MangaGamer in 2009. The gameplay in
Shuffle! follows a branching plot line which offers pre-determined scenarios and courses of interaction and focuses on the appeal of the female main characters.
Shuffle! has been re-made into an expanded version called
Shuffle! Essence+. It has expanded routes for the original five main heroines as well as new routes for six other characters.
Shuffle! also has three
spin-off sequels:
Tick! Tack! ,
Really? Really! and
Shuffle! Love Rainbow.
