We close the chapter with something that sounds soft but is deadly serious: happiness. It is easy to overlook, yet it directly decides how long your recruited citizens live. Get this right and your workforce is stable and long-lived; get it wrong and you will watch people die mid-job and wonder why. Let us make sure you are firmly on the right side of that, because this is the lesson that separates a thriving town from a leaky one.
What happiness is
Your town's happiness is simply the average level of all your houses, multiplied by 10. That one formula gives you everything. If every house is level 1, your happiness is 10 percent. If every house is level 5, it is 50 percent. If every house is level 10, you hit 100 percent. And if you have no houses at all, happiness is 0. This is the second reason, promised back in lesson 5, that taller houses are worth building - they raise happiness as well as adding rooms, doing two good jobs with one upgrade.
- All level 1 houses gives 10 percent happiness.
- All level 5 houses gives 50 percent happiness.
- All level 10 houses gives 100 percent happiness.
- No houses at all gives 0 percent.
Happiness is lifespan
Here is the part that makes happiness matter so much, and it is the single most important idea in this whole chapter about people. Happiness is lifespan. A recruited citizen lives for roughly a number of days equal to your happiness percentage at the moment you recruit them. So at 50 percent happiness, a new recruit lives about 50 days. At 100 percent happiness, a recruit lives about 100 days. The higher your happiness, the longer your people stick around to work for you - happy towns are simply towns where workers last.
Lifespan is locked in at recruitment
A recruit's lifespan is fixed by your happiness at the moment they are recruited - and it does not update later. So raise your happiness BEFORE you recruit, not after. Recruiting at 20 percent and upgrading houses tomorrow does nothing for the people you already brought in; they keep their short clock.
Sit with that timing rule, because it is the heart of this lesson and the easiest place to slip up. Imagine recruiting a batch of workers while your happiness is only 20 percent. Those workers are stamped with a roughly 20-day life the instant they arrive, and nothing you do afterward extends it. Now imagine first upgrading your houses to push happiness to 80 percent, and then recruiting the same batch - those workers carry a roughly 80-day life instead. Same people, same effort, four times the working life, just from doing things in the right order. Order is everything here, and it costs you nothing to get it right.
What happens when a citizen dies
When a citizen does reach the end of their life, two things happen, one mild and one painful. Their home frees up, which opens a room again for a future recruit - that part is tidy enough. And if they were staffing a building, there is a sting: any production run in progress stops immediately and yields nothing. The building simply drops back to needing workers, and whatever was mid-production is lost. So a worker dying at the wrong moment can cost you a whole run, which is why low happiness is so quietly expensive.
A death can kill a run
If a citizen who is staffing a building dies, the production run in progress halts at once and produces nothing - the building falls back to needing workers. This is the real cost of low happiness: not just shorter lives, but lost production when people die on the job.
Founders are forever
Let me put the timing rule into the shape of a habit, because a habit is easier to keep than a fact. Whenever you are about to recruit, ask yourself one quiet question first: is my happiness as high as I can reasonably make it right now? If a house is sitting at a low level and you have the means to upgrade it, doing that before you recruit stamps every new worker with a longer life. The order is the entire trick. Upgrade houses, then recruit. It is such a small reordering of two things you were going to do anyway, yet it can double or triple how long your workforce lasts. No other single habit in this chapter pays back so much for so little effort.
There is one comforting exception to all this mortality. Your founders - the starting free citizens from lesson 7 - never age and never die. Everyone you recruit ages and eventually dies, but your founders are permanent, a steady presence no matter how the years turn. It is a nice symmetry with their earlier limitation: founders cannot be hired into buildings or trained, but in exchange they are immortal. So the people you bring in are your mortal, hireable workforce, and the founders are your unchanging core - two kinds of citizen, each with their own gift.
It is worth letting the bigger picture of happiness sink in, because it ties this whole chapter together in a way that is genuinely elegant. Notice how one decision - the level of your houses - reaches into three different systems at once. House level sets your rooms, which caps your population. House level sets your happiness, which sets how long your recruits live. And longer-lived workers mean fewer deaths interrupting your production runs, which keeps your whole economy steady. So when an early lesson nudged you toward building houses tall rather than wide, this is the deeper reason: a single tall house quietly improves your population, your lifespans, and your production reliability all together. Few choices in the game are so quietly powerful.
Pulling it all together, and this is the habit I most want you to carry out of this chapter: keep your house levels high, because high house levels mean high happiness, and high happiness means your recruits live long and productive lives. The single most valuable habit you can form is to upgrade your houses first and recruit second, so every new worker is born into a long life. Do that, and your town will hum along with a stable, contented population that rarely lets you down.
That covers the living heart of your town. You now understand the core loop, energy, land, building, houses, recruiting, professions, production, upgrades and repair, and happiness - the full foundation of a thriving CoinRepublik town. You came in worried you might be behind, and look at you now: you can run the whole wheel. There is just one more quiet system worth meeting before we close, and it is a gentle, encouraging one: the way your town slowly climbs in level as you play.
