Clangen Simulator

You name your Clan, drop it into a marsh territory, and by the third moon your deputy is already dead from greencough while two kits wait to be apprenticed. This is the rhythm of Clangen Simulator, a feline life-management game where nothing is scripted and every generation is one bad roll away from collapse.

Genre	Life simulation, clan management
Setting	Wild cat Clans in forest, marsh, or mountain biomes
Core Loop	Monthly events, patrols, and role assignments
Session Length	Ongoing, generational play

The game hands you a starting roster of randomly generated cats, one of whom becomes leader and receives nine lives from StarClan, the spirit ancestors who watch over the Clan from beyond. You don’t control what happens between cats directly. Instead you click through the Events Tab each moon and watch patrols return with prey, injuries, prophecies, or the occasional stray kit that gets adopted on the spot. It’s less a game you win and more a game you keep alive, one litter at a time.

Roles and the Structure of Clangen Simulator

Every cat in Clangen Simulator eventually settles into a role: kit, apprentice, warrior, medicine cat, deputy, or leader. Kits can’t do much beyond wander around camp, but once they’re apprenticed they start training under a mentor and can be sent on their first patrols. Warriors handle hunting and border patrols, while the medicine cat manages the Medicine Cat Den, tending injuries, gathering herbs, and interpreting omens sent down from StarClan. Losing your only medicine cat mid-outbreak is one of the more brutal ways a save can spiral, since untreated greencough or whitecough can wipe out half a Clan before the next moon rolls around.

The deputy slot matters more than new players expect. If your leader dies without a named deputy, the Clan is left without a clear line of succession, and the game does not go easy on you for forgetting to fill the role. Veteran players tend to name a backup deputy candidate early just in case a leader burns through all nine lives faster than planned, which happens more often than the tranquil marsh-camp screenshots would suggest.

Combat and danger come through patrols sent out from the Leader’s Den, where you choose which cats go out and, in some versions, what kind of patrol they run — hunting, border, or herb-gathering. Rogues, badgers, and rival Clan cats can all turn a routine patrol into a funeral. Some players describe this as the game’s “moon roulette,” since a single bad patrol roll can undo months of careful clan-building in an instant.

Family Trees and Clangen Simulator’s Long Game

What keeps people playing Clangen Simulator for dozens of generations is the family tree system. The game automatically tracks lineage, so a kit born in moon four might grow up to lead the exact Clan its great-grandmother once led. Players in the community often talk about “Clan lore” the same way you’d talk about a long-running D&D campaign — cats develop reputations, rivalries, and running jokes purely from how the randomization played out.

• Genealogy trackers spend as much time in the Cats Tab reading backstories as they do playing moons forward.
• Reputation-focused leaders obsess over keeping Clan standing high, since a low reputation can trigger rebellions or hostile encounters with neighboring Clans.
• Speedrunners of a sort try to push a single bloodline to leadership as fast as possible, accepting heavy kit losses along the way.

By the time a Clan reaches its third or fourth generation, most players have stopped thinking of their cats as disposable and started treating losses the way the community does — as canon events worth remembering rather than failures to reload past.

What New Players Get Wrong

The most common beginner mistake is ignoring herb stock. Early on it feels optional, since nothing bad happens for several moons. Then an outbreak hits during leaf-bare and there’s no catmint left, and the Clan loses three cats in a row. Herb management, particularly stockpiling before leaf-bare, is one of those systems that looks decorative until it isn’t.

The other common misstep is spreading warriors too thin across roles that don’t need them yet. A small Clan with too many mentors and not enough active hunters starves quietly rather than dramatically, and by the time the game’s warnings register, the damage is already generational.

What happens when a Clangen Simulator leader loses all nine lives?

The Clan enters a leadership vacancy and the named deputy is called to the Moonstone-adjacent ceremony to receive their own nine lives from StarClan. If no deputy was named, the game forces a scramble to appoint one, often from whichever surviving warrior has the least baggage, which can produce some genuinely strange leadership choices.

Can cats in Clangen Simulator die of old age instead of combat or illness?

Yes. Elders who retire from active duty still age normally, and natural death from old age is one of the more common, low-drama ways a long-lived cat exits the story after a full life of patrols and mentorship.

Does Clangen Simulator let you control biome choice at the start?

You pick a territory type — forest, marsh, or mountain — before founding your Clan, and it quietly shapes which prey and dangers show up in patrol events for the rest of that save.

Clangen Simulator rewards the kind of player who’s willing to lose a beloved warrior to a badger attack and keep clicking anyway, because the next moon might bring a prophecy that changes everything. It’s messy, occasionally heartbreaking, and completely uninterested in giving you a clean win state — which, for a game built entirely around StarClan’s unpredictable will, feels exactly right.
