📜 General rules

  • Your progress in each section increases your overall XP, which unlocks the next sections.
  • A daily login bonus is granted on your first connection of the day. Its amount scales with your overall progression.
  • Improve your sections to grow this daily bonus.

🏙️ City

  • Every building category can be upgraded several times — you choose freely which category to advance.
  • Every category upgrade costs Kii, Materials AND Wood; all three costs increase with the total number of buildings already built in your city.
  • Every construction takes time (from a few seconds to several minutes depending on your city's size) — several constructions can run at once depending on your Capacity (Staff/Special Upgrades).
  • Kii produced by your city are credited automatically every time you log in, based on elapsed time (capped at 24h of production).
  • Every building belongs to a category (Habitat, Culture & Leisure, Economy, Wellbeing, Administration, Safety, Tourism) and gives a bonus to the matching indicator: population, happiness, Kii/h harvest or visitors depending on the category.
  • Economy buildings generate a bit of pollution, which slightly reduces your city's Happiness.
  • If your city's Happiness drops below a certain threshold, unrest kicks in and reduces your Kii/h harvest — upgrade the categories that boost happiness to lift it.
  • Your population consumes Food (harvested in the Resources section); if it runs short, your city's Happiness drops.
  • Freely toggle free, reversible municipal policies: each one grants a real advantage in exchange for a trade-off on another indicator.
  • You can rename your city anytime.

🌾 Resources

  • 3 independent harvesting lines: the Farm produces Food, the Sawmill Wood, the Mine Materials — each with its own building to upgrade.
  • A built line harvests nothing until its dedicated worker (Farmer, Woodcutter or Miner) is hired — they're the one making the trip to the resource.
  • Once hired, the worker harvests in a continuous loop. Upgrade the building and the worker's level to go faster and harvest more.
  • Harvested Food, Wood and Materials are used across other sections: City construction, feeding your Zoo animals/Kiimo/inmates, and Trading Post exchanges.

📖 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.

⚖️ Trading Post

  • The Trading Post is available from the start: 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 Trading Post 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 Trading Post mastery.

🔬 Technologies

  • 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 in the Resources section.
  • 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.
  • 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 in the Resources section 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.

🏎️ Race

  • 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.

🗺️ Exploration

  • Choose a planetary exploration (short, fewer Kii) or a space mission (long, more Kii).
  • The mission takes several hours. Progress is shown with a countdown timer.
  • Once the mission ends, confirm it using the dedicated button to advance this section.
  • Only one exploration can be active at a time.

⚔️ 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.

⛓️ Penal Colony

  • 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; if it runs short, their danger temporarily rises, increasing incident risk.
  • Search the cells regularly, for free: you may find loot or stop a scheme before it happens.

Quick FAQ

Essential answers to get started smoothly.

How to progress quickly at the beginning?

City, Resources and Stories are available from the start, no XP required. Start by building in the city (Kii credited automatically every time you log in) and develop your Farm in Resources to lay the groundwork for your economy.

Why are some sections locked?

Each section requires an XP threshold. Keep progressing in active sections to unlock them.

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?

Build and upgrade your city's buildings, starting with the Economy category (Kii credited automatically every time you log in), and enjoy the daily login bonus granted on your first connection 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?

What are Materials, Wood and Food for?

These are 3 resources produced by the Resources section (Farm, Sawmill, Mine). Materials are used to build in the City (alongside Kii); Food feeds your Zoo animals, your Kiimo Companion and your Penal Colony inmates. You can trade all 3 for Kii (and back) at the Trading Post.
