ℹ️ General rules
- Your progress in each section increases your overall XP, which unlocks the next sections. Market, Laboratory, Zoo, Circuit, Exploration base, Arena, Prison and Auction hall also require the building of the same name in your City.
- 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: assign your settlers to the starting buildings, upgrade your resource buildings, then grow your population with Housing — the "Getting started" guide on the City page details these steps.
- Your city is a 36-plot grid: build on any free plot, choosing among 18 possible buildings (Farm, Sawmill, Mine, Market, Housing, and 13 passive buildings).
- A built building produces nothing until a settler is assigned to it — assign one from the Buildings tab to start its production.
- Farm, Sawmill, Mine and Market harvest in automatic cycles (Food, Wood, Materials, Kii); the other 13 buildings continuously contribute to a stat (Safety, Health, Happiness, Education, Science, Environment, Energy).
- Welcome new settlers (one at a time or as many as possible, each costs Kii and Food), up to your Housing capacity — each settler welcomed then needs to be assigned to a post to be useful.
- Past 6 buildings built, an Energy deficit (Power Plant) reduces all production, and an Environment deficit (Park) reduces Happiness — build more of them to avoid these penalties.
- Special upgrades reduce construction duration and cost, and increase housing capacity as well as the number of job slots.
📖 Stories
- Each chapter offers 1 to 2 choices that change what happens next.
- Stories are played in order, one after another.
- Some choices can send you back to the start of the story.
⚖️ Market
- The Market unlocks at a specific XP threshold, once the Market building is built in your City: it lets you exchange Kii for Materials, Wood or Food (and vice versa) to quickly stock up.
- The reference price is fixed and identical for all 3 resources — it never fluctuates over time.
- The buy price is slightly above the rate, and the sell price slightly below: 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 scales with level.
- Each completed tier advances this section and increases your overall XP.
👾 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.
- Kiimo evolves through stages based on accumulated affection points, with a permanent cosmetic branch choice at stage 3.
- Kiimo can occasionally fall sick: heal it to speed up recovery.
🦁 Zoo
- The Zoo unlocks at a specific XP threshold, once the Zoo building is built in your City.
- Each animal has a habitat and must be placed in a suitable enclosure.
- Compatible animal groups can share the same enclosure.
- Animals consume the Food harvested by your City's Farm every 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.
- Global limits apply to enclosures and the total number of animals.
- 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.
- Upgrade your vehicle engine and reliability for better results.
- Results are calculated once a day. The best drivers earn podiums and wins.
- 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) or a space mission (longer, pricier, but better rewards) — space has far more to explore than a single planet.
- Before departure, pick a route: cautious (cheaper and safer, but longer and less rewarding), standard (balanced) or fast (pricier and shorter, but more rewarding).
- The mission takes several hours and reveals a terrain crossed as well as a distance traveled. Progress is shown with a countdown timer.
- When it returns, choose your extraction mode: cautious (guaranteed reward) or fast (risk coming back with less... or a lot more). Small events can also occur along the way and slightly change the final reward.
- 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.
- Any completed claim 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, attack, and defense are fixed: only the difficulty you choose affects your odds of winning.
- Three difficulty levels: Easy, Medium, Hard. The higher the difficulty, the stronger the opponent.
- Each victory earns Kii and ranking points (+10 pts). A defeat causes a small point loss (-5 pts).
- The arena ranking is based on your accumulated score. 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 3 sectors: Security (housing capacity), Workshops (Kii production), Rehabilitation (reduces danger).
- 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.
- Your inmates also consume Food (taken from your stock at each harvest), with no other consequence if it runs out.
- 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 9 PM.
- Each bid adds a fixed amount (+500, +1,000, +5,000 or +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, no XP required. Start by assigning your inhabitants to your City's Farm, Sawmill, Mine and Market: they continuously harvest Food, Wood, Materials and Kii, the groundwork of your economy.
Why are some sections locked?
Each section requires an XP threshold. 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 current XP is below the required threshold. Keep progressing in already unlocked sections.
How can I earn Kii quickly?
Assign residents to your city's Markets and upgrade them: they produce Kii continuously. Also enjoy the daily login bonus granted on your first visit of the day.
What exactly does ranking show?
It compares profiles by XP 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, Wood and Food for?
These are 3 resources harvested by the Farm, Sawmill and Mine 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 all 3 for Kii (and back) at the Market.
