A Solitaire Mystery is a clever and unexpectedly varied take on the humble solitaire genre. Rather than offering one long-running ruleset, it collects over 20 unusual solitaire card games: some play like familiar decks and standards, while others are experimental reworkings that bend the rules into new directions. Along the way you’ll do things you don’t normally associate with solitaire - grow and harvest plants, face eldritch monsters, perform alchemy, and even play poker - which keeps each session feeling fresh.
