Game sections
Discover every facet of the adventure.
City
Build and upgrade your buildings, welcome settlers and feed them: your workers staff your open buildings, your city produces your resources and opens the other sections.
Stories
Live interactive stories: each choice costs Kii and moves the tale towards one of its endings, within the day's choice limit.
Market
Buy and resell Materials and Food at a fixed price. Stock up or sell off your surplus whenever you need to.
Laboratory
Launch research, one at a time, for Kii and Materials, to climb the Laboratory levels.

Buy enclosures, welcome animals, feed them and heal them to grow your zoo.
Circuit
One race a day against the other players: pick your style, upgrade your vehicle and aim for the podium.

ℹ️ General rules
- Your global progress is the average of your 11 sections: it unlocks the next sections. Special upgrades give bonuses but do not count in the progress. Market, Laboratory, Zoo, Circuit, Exploration base, Arena, Prison and Auction hall also require the building of the same name in your City. A finished section stays playable.
- A daily login bonus is granted on your first visit of the day, even if you stayed logged in since the day before. Its amount scales with your overall progression.
- Improve your sections to grow this daily bonus.
- The weather of Karia, shown at the top of every page, changes every few hours and is the same for every player. It is purely decorative: it has no effect on the game.
🏘️ City
- To get started: your settlers already work in the starting buildings; welcome new settlers (at first, births are too rare to grow the city), upgrade your resource buildings, then grow your population with Housing — the getting-started steps on the home page walk you through the first ones.
- Your city is a 36-plot grid: click any free plot to build on it, choosing among 29 possible buildings (Farm, Mine and Market produce resources, Housing welcomes inhabitants, the others provide a city stat).
- Your city grows by tiers according to its population (Hamlet, Village, Town, City): each tier unlocks new buildings. A building that opens another section is available as soon as your overall progress reaches that section's threshold.
- All your working-age settlers work in your open buildings (all but Housing), shared at the same occupancy rate: a building's production or stat follows that rate, up to 100% at full staff, and each level adds posts. Close a building (from its plot or the Buildings tab) to send its settlers to the others; beyond the open posts, workers are unemployed, with no other effect.
- Farm, Mine and Market harvest in automatic cycles (Food, Materials, Kii), which keep running while you are away, up to 24h of production, and while the building is being upgraded (at its current level until the work ends); the other buildings continuously contribute to a stat (Safety, Health, Happiness, Education, Science, Environment, Energy).
- Welcome new settlers (as many as you choose, up to the maximum possible, for Kii and Food), up to your Housing capacity — they join your population, split into fixed shares (toddlers, pupils, workers, retirees), and only the workers have a job.
- Your population is a single number, split into fixed shares: 10% toddlers, 15% pupils, 55% workers and 20% retirees; only workers work. Every day, some settlers die (fewer with Health), each settler eats 50 Food (those the stock cannot feed starve), then children are born (more with Happiness), within the free places of your Housing. While you are away, the city keeps living.
- Each stat comes from its own buildings only and acts on a single parameter, from its starting value up to the maximum once its whole group is built at max level and full staff: Health → deaths, Happiness → births, Education → resource production, Science → Energy need, Security → harvests lost, Environment → pollution, which removes Housing places. Every stat applies from the start, at its starting value until its buildings are built.
- Past 10 building levels (Housing, Power plant, Solar plant and Wind farm excluded), each level needs Energy (less with Science): if your Power plant, Solar plant and Wind farm do not produce enough, resource production drops — build and upgrade them as your city grows.
- Special upgrades reduce construction duration and cost, and increase housing capacity as well as the number of posts (beyond full staff, production keeps rising).
📖 Stories
- Each chapter offers 1 to 2 choices that change what happens next.
- Every story is available from the start. Only one is in progress at a time: you can switch from the list, your progress in each one is kept.
- Some choices can send you back to the start of the story.
⚖️ Market
- The Market unlocks at a specific global progress threshold, once the Market building is built in your City: it lets you exchange Kii for Materials or Food (and vice versa) to quickly stock up.
- Buy and sell prices are fixed and identical for Materials and Food; buying costs a little more than selling earns: that is the Market margin.
- Your purchases are limited by your storage capacity for the bought resource, and your sales by your maximum Kii reserve.
- Each trade of a sufficient quantity advances your Market mastery, up to a few counted trades per day.
🔬 Laboratory
- Each tier costs Kii and Materials, more and more with the level.
- Each completed tier advances this section and your global progress.
👾 Companion
- Feed, play with and wash Kiimo to earn affection points — every care action is free of Kii.
- Feeding Kiimo consumes the Food harvested by your City's Farm.
- Every care action costs energy. Once depleted, Kiimo takes a nap for a few hours before waking up rested, with no penalty at all.
- While you are away, its gauges wear down for at most 24h, never below their floor.
- Kiimo evolves through stages based on accumulated affection points.
- Kiimo can fall sick: its gauges wear down faster and care actions earn half the affection. Healing it costs energy.
🦁 Zoo
- The Zoo unlocks at a specific global progress threshold, once the Zoo building is built in your City.
- Each animal has a habitat and must be placed in a suitable enclosure; an enclosure costs Kii and Materials.
- Compatible animal groups can share the same enclosure.
- Once a day, when you visit, the animals eat the Food harvested by your City's Farm: those the stock cannot feed die of hunger, the oldest first (a long absence counts as a single day).
- An animal can get sick and must be healed before the critical delay.
- Births depend on adults present and enclosure capacity — never guaranteed, each eligible animal retries its chance every day.
- The Zoo progress counts the animals welcomed in total (bought or born): it never goes down, even when an animal dies or is sold.
- You can sell an animal to recover part of its purchase price.
🏎️ Circuit
- A race event takes place every day. Register before the deadline to participate.
- Choose your driving style from prudent, balanced, or aggressive before each race.
- Your power comes from your vehicle (engine and reliability, each level costs Kii and Materials) and the Upgrades; the chosen style only changes the share of luck.
- Results are calculated once a day. A podium earns Kii, in proportion to the entry fee: the amounts are shown with the daily race. Opponents have a fixed level, so every vehicle upgrade improves your chances.
- A win (1st place) has a small chance of getting you a 100% cosmetic rare item, viewable in your collection (Storage page).
🗺️ Exploration base
- Choose a planetary exploration (short, cheaper, it brings back Materials and Food) or a space mission (longer, pricier, it brings back Kii) — space has far more to explore than a single planet.
- Before departure, pick a route: cautious (cheaper, but longer and less rewarding), standard (balanced) or fast (pricier and shorter, but more rewarding).
- The mission takes several hours. The countdown is in the top bar; when it returns, the loot is credited automatically on your next visit, and a notification sums it up.
- Every completed mission is added to your Exploration journal (Statistics tab), which keeps track of your last 20 missions.
- Only one exploration can be active at a time.
- Every completed mission has a small chance of getting you a 100% cosmetic rare item, viewable in your collection (Storage page).
⚔️ Arena
- Fight creatures in turn-based combat. Each turn you choose an action: Attack, Defend, Dodge, or Special.
- Attack deals normal damage. Defend reduces incoming damage and boosts your next attack. Dodge gives a chance to avoid the enemy attack. Special is a powerful attack with a cooldown.
- Your HP are fixed; your attack and defense grow with the power Upgrades.
- Three difficulty levels: Easy, Medium, Hard. The higher the difficulty, the stronger the opponent.
- Each difficulty level has its own entry fee and reward, both rising with your progress: a victory always earns more than the fight cost. A defeat earns nothing.
- The number of fights per day is limited.
- Each combat victory has a small chance of getting you a 100% cosmetic rare item, viewable in your collection (Storage page).
⛓️ Prison
- Upgrade 2 sectors: Security (security and housing capacity), Workshops (Kii production); each level costs Kii and Materials.
- Capture inmates or let them arrive automatically, up to your housing capacity.
- Interned inmates produce Kii over time — harvest regularly to collect it.
- If danger exceeds your security, an inmate may be placed in isolation or escape with part of the pending harvest.
- Every day, each inmate eats Food from your stock: those it cannot feed starve to death, the longest-held first.
- Search the cells regularly, for free: you may find loot or stop a scheme before it happens.
🔨 Auction hall
- A new artifact goes up for auction every day, with a fixed starting price of 50 000 Kii. Bidding closes at 21:00.
- The artifact of the day is drawn among those not yet offered in the current cycle: each one comes back once per cycle, and a cycle has as many days as there are artifacts.
- Each bid adds a fixed amount (+5 000, +10 000) to the current highest bid — no free amount, and you cannot outbid yourself if you are already leading.
- Your Kii are only charged at closing time, and only if you win the lot. If you no longer have enough Kii by then, you lose the artifact.
- A mystery collector sometimes outbids you, especially if the auction has been quiet for a while — they can win the lot too.
Quick FAQ
Essential answers to get started smoothly.
How to progress quickly at the beginning?
City and Stories are available from the start. In your City, the adults work by themselves in the open buildings: the Farm, the Mine and the Market continuously harvest Food, Materials and Kii, the groundwork of your economy. Welcome inhabitants and upgrade these buildings to produce more.
Why are some sections locked?
Each section opens at a global progress percentage (the average of your 11 sections). Keep progressing in active sections to unlock them. Some also require building their matching building in your City.
Where can I see new features?
The latest updates are displayed directly on the home page.
How do I track my progress?
Use the History tab on your profile, plus the Ranking page, to get a clear overview of your progression.
How does global progression work?
Each playable section contributes to the average progression shown on the home page.
Why can't I access a section?
Your global progress is still below the required threshold. Keep progressing in already unlocked sections.
How can I earn Kii quickly?
Keep your City's Market open and upgrade it: it produces Kii continuously, according to the number of adults working there. Also enjoy the daily login bonus granted on your first visit of the day.
What exactly does ranking show?
It compares profiles by global progress and then Kii to provide a clear hierarchy.
What is the Public Profile for?
It lets you view a player's stats, badges, and progression state.
What should I do if an action fails?
Check your Kii, section unlock status, and the conditions shown under the action button.
How can I secure my account?
Use a strong password, a valid email address, and update your password from Settings when needed.
What are Materials and Food for?
These are 2 resources harvested by the Mine and the Farm in your City. Materials are used to build (alongside Kii); Food feeds your Zoo animals, your Kiimo Companion and your Prison inmates. You can trade both for Kii (and back) at the Market.
