Play as a cultist working to unseal ancient gods by gathering spirit from a deck of cards. Each round has a spirit target; fail to meet it in time and the run ends.
Cards enter a roulette wheel in a chaotic order. Arrange their positions to steer outcomes and make the most of interactions among creatures, humans, spells, and other cards.
Build your deck as you play, collect relics that alter the game, and make choices at Cthulhu-themed events. Different card combinations support distinct approaches, while the wheel’s randomness makes each round less predictable.
Players who enjoy Fhtagn Simulator often point to its roulette-based deckbuilding and the card interactions that let them shape different builds. Some find the unpredictable outcomes entertaining and the runs easy to pick up, while others feel randomness, limited variety, or uneven balance can make the experience frustrating. Reviews also mention unclear English card text and occasional technical or interface problems.
