The original soundtrack of A Solitaire Mystery, composed by Hazelstorm. A Solitaire Mystery is a collection of over 20 unusual solitaire cardgames, ranging from somewhat standard ruleset playable with a traditional deck of cards to mysterious experimental takes on the genre and funky reimplementations of other games in solitaire form. Among other things, ASM makes you grow and harvest plants, defeat eldritch monsters, perform alchemy and play poker over the course of its solitaires.
