shuffle

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.

Shuffling is a procedure used to randomize a deck of playing cards to provide an element of chance in card games. Shuffling is often followed by a cut, to help ensure that the shuffler has not manipulated the outcome.
