About Fhtagn Simulator
Fhtagn Simulator is a single‑player roguelike card game that blends deck‑building ideas from titles like Luck be a Landlord, Slay the Spire, and Monster Train. Players must gather spirit before a timer runs out, or the ancient gods will punish them with game failure.
The Cthulhu‑themed world features a chaotic roulette that determines card order, a sacrifice system for breaking seals, mythic monsters, event choices, and relics granted by evil gods that can alter gameplay. It runs on Windows and supports Steam achievements, cloud saves, and family sharing.
01 / THE GUIDE
Roulette Mechanics
Cards enter the wheel in a chaotic order, reflecting the disorder of the Cthulhu mythos. This randomness defines the default pool of cards each round.
Players can set the card slots on the roulette to guide which cards emerge, turning pure chance into a strategic decision point that influences the immediate pool.
- Experiment with different slot layouts to see how the card pool changes.
- Adjust slots early in a run to shape later options.
02 / THE GUIDE
Spirit Collection & Time Limit
A spirit meter tracks progress; enough spirit must be collected before the timer ends. Failing to meet the threshold triggers punishment from the ancient gods and ends the run.
The time limit creates pressure to make efficient choices each round, encouraging players to prioritize cards and actions that generate spirit quickly.
- Focus on early‑round cards that produce spirit.
- Watch the timer closely to balance risk and reward.
03 / THE GUIDE
Sacrifice System
Tributes are offered as sacrifices to break seals that block progress toward summoning evil gods. This act advances the narrative goal rather than directly fighting Chaos.
Each tribute advances the mission of breaking the seal and summoning the evil gods.
- Consider which tributes to offer as you work toward breaking the seal.
- Consider saving spirit for later sacrifices if early options are weak.
04 / THE GUIDE
Relics
Relics are rewards granted by the evil gods that have the ability to change the game. Using them well can help you get more spirit.
Because each relic’s impact is distinct, testing them in separate runs helps determine how they influence deck performance.
- Try a single relic per run to isolate its effect.
- Note any changes to spirit gain when a relic is active.
05 / THE GUIDE
Cthulhu‑Style Events
During a run, players encounter events styled after the Cthulhu mythos. Choices made in these events can shape how the run unfolds.
Event outcomes add narrative flavor and can shift the balance of power for subsequent rounds, influencing both spirit gain and deck composition.
- Read event options carefully to anticipate possible rewards.
- Balance immediate gains against longer‑term deck needs.
