Arkham Noir is a solitaire card game inspired by the interconnected stories of H.P. Lovecraft and other authors, re-imagined as noir detective stories. Each case stands alone. Gameplay consists of adding cards to open cases, creating lines of investigation, in an effort to solve them. The ultimate goal is to score five puzzle Clue cards in order to piece together the Big Picture, before running out of time or mental stability. Each newly shuffled deck is the start of a unique challenge, with adjustable difficulty levels to accomodate all level players. In Infinite Gulfs of Darkness Howard Lovecraft investigates events based on the stories From Beyond (1920), Nyarlathotep (1920), The Haunter of the Dark (1935), and Robert Blochs The Shadow from the Steeple (1950).
