Circle of Blood is a 2D adventure game played from a third-person perspective. The player uses a point-and-click interface to interact with the environment and to guide protagonist George Stobbart through the game's world. To solve puzzles and progress in the game, the player collects items that may be combined with one another, used on the environment, or given to non-player characters. The protagonist converses with NPCs via dialogue trees presented through "conversation icons" to learn about the game's puzzles and plot. Clues and other information are obtained by clicking on items in the inventory and on objects in the environment. The player navigates with a map, to which new locations are added as the story unfolds. Unlike in most adventure games at the time, the protagonist's death is possible, after which the player starts from the last save point.

The Witness was the seventh game released by interactive fiction pioneers Infocom. The player character is a detective who has been summoned to the Cabeza Plana, California office of Mr. Linder, a millionaire. Linder fears that his life is in danger... and indeed, as he sits in his office with the player, he is murdered before the player's eyes. The player then must solve the murder.

The follow up to Danganronpa: Trigger Happy Havoc. The main character, Hajime Hinata, a new 'Ultimate' student at Hope's Peak Academy. On their first day, Hajime and all of his classmates are taken on a field trip to the mysterious Jabberwock island by their anthropomorphic rabbit teacher, Usami. Usami explains that on this island the students are to have fun together and become friends to gather Hope Fragments. Usami's field trip does not go as planned when Monokuma appears and begins a new Killing Game. Anyone that wants to leave the island must commit a murder and get away with it. If the murderer is successful, he/she is allowed to leave the island, while everyone else is killed. When a murder occurs, the player investigates. After the investigations, a trial commences to determine who the culprit is.

The game is a murder mystery visual novel with a heavy story focus that requires multiple playthroughs to figure out and involves puzzle rooms used to progress through the story with dialogue choices to be made inbetween them.

In Danganronpa, players dive into a series of class trials and expose the lies and contradictions of their classmates to find out who's behind each grisly murder. In each trial, players must use the evidence and testimony collected during their investigation to shoot down their opponent's assertions literally.
