Gyakuten Saiban in Joypolis

Gyakuten Saiban in Joypolis is a unique Ace Attorney game experience exclusively available in the Tokyo location of Sega's Joypolis chain of amusement parks. Although at its core it's a traditional Ace Attorney investigative game, its most unique aspect is its integration with the park. Players start their game in a replica of Phoenix Wright's law office, where they select one of three cases and are given a physical passport that can track their progress. They then travel between stations spread out over the third floor of the park to gather clues and interrogate witnesses and suspects. Each station has an arcade machine featuring a touchscreen and a spot to scan the passport; upon scanning their passport, players are taken to an investigation or a conversation with one of a few witnesses for the case. Like in the traditional Ace Attorney games, gameplay is primarily visual novel-style dialogue with branching dialogue options. After completing all of the stations on the floor, players can return to the office in order to complete the case. The story uses characters from other games in the series, but is considered non-canon; characters' backstories sometimes conflict with how they were previously depicted.

There are three cases available; each session allows the players to play through one of them.

• Fly High of the Turnabout: When a murder occurs at Tokyo Joypolis's Steel Samurai show, Mako Suzuki (Maggey Byrde) lands under suspicion and it's up to the player to clear her name.
• The Turnabout Locked Room: The manager of Tokyo Joypolis, Rando Daiba, is murdered in a locked room and it's up to the player to identify the murderer.
• The Turnabout Don: A murder occurs during a martial arts performance at Tokyo Joypolis. The key to the case is Kogyoin Don, king of the entertainment industry, but it's unclear whose side he's on.
