Shuffle!

Shuffle! (シャッフル!, Shaffuru!?) 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 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.

Shuffle! has made several transitions to other media. There have been two manga series based on the visual novel. The first was serialized in Kadokawa Shoten's magazine Comptiq between December 2003 and 2006. The second was a comic anthology published by Kadokawa Shoten between July 2004 and December 2005. Two anime adaptations were produced by the animation studio Asread. The first anime was twenty-four episodes in length and was broadcast in Japan between July 2005 and January 2006. The second series was a twelve-episode readaptation and was broadcast between January and March 2007. Seven light novels, two fanbooks, nine drama CDs, and seven radio drama CDs adaptations have also been produced.

The visual novel was well received whereas the first anime adaptation received mixed reviews.
