Delphi no Shintaku

Delphi no Shintaku (デルフォイの神託, translated as "The Delphic Oracle") is the only "Quiz Adventure" title produced by Eiji Fukuzawa. Its namesake is a reference to priestesses of Apollo who were said to be the oracles for the god.

The protagonist is the Ancient Egyptian king's emissary. His mission is to personally visit the Seven Mysteries of the Ancient World and report their findings to the king. Players can decide their protagonist's name within the start menu.

Gameplay
Controls are simple. Movement is done by clicking on points on the world screen with the mouse or by using a keyboard to direct the protagonist. Click/select a person to converse with them.

Townspeople provide hints for locating the Seven Mysteries. Most people will challenge the player to a two-question trivia quiz which must be correctly answered in consecutive order. The player must select the correct answer within a ten second time limit. The player can retry immediately after their failure with no penalties. Talisman can be earned by completing random quizzes and can be used before quizzes to delete a false answer.

Figures standing before the Seven Mysteries may ask three specific questions regarding their artifact. If the player is paying attention to the townspeople, they can answer them correctly without difficulty. Certain guardians will pose a different mini-game challenge such as a matching game or flag identification. If they fail to complete it, the keeper will often issue an easier secondary challenge for the player. Challenges vary at each location.

Once the main story is completed, the player can choose to restart the story again for a better ending score or start another player account from scratch.
