Zero Escape: Nine Hours, Nine Persons, Nine Doors - The Novel (2013)

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. The iOS version of the game removed the puzzle rooms to focus more on the visual novel aspects of the game. The puzzle rooms are replaced with narration of the events that take place instead. The iOS version of the game also has an exclusive ending.

Storyline

"Nine individuals, seemingly strangers, find themselves awakening to a rude truth – they’re trapped on a ship that will sink in nine hours, and must play a deadly game in order to escape. Kidnapped by the mysterious Zero, these nine must solve puzzles and uncover the location of the elusive ninth door before time runs out. Each player is tied to a bracelet that controls a bomb within their bodies. One wrong move and they explode. However, beyond this life-or-death game lies questions that they must answer: Why have they been brought here and, more importantly, who is Zero?"
