What you do

  1. 01Landing

    Moor the traffic

    Dugout trading canoes tie up at your landings for provisions, repairs and a hot meal, and pay on departure. One landing, one vessel at a time; every landing needs an open side for the approach.

  2. 02Trade

    Trade the cargo

    Vessels sell what their home city exports and buy what it imports. Set Buy and Sell per good, hold obsidian for a workshop, and ride the booms.

  3. 03Income

    Tap the banks

    Every building earns cacao by the minute into its own bank. A glowing coin means it is ready: tap it and watch the cacao flies home. Banks keep filling while you are away.

  4. 04Timers

    Build on the clock

    Buildings take real time to open, from ninety seconds to four hours by tier, and upgrades take longer still. Queue a build, go live your life, come back to a brighter city. Jade skips the wait.

  5. 05Voyages

    Paddle out

    Send voyages from your landings to any of eight regions. They come back with cargo, charts, Jade and discoveries for the Codex: vessels, peoples, heirlooms.

  6. 06Maya world

    Claim new rivers

    Clear rings of unclaimed land around your plaza as the city grows, then found the next city in one of eight regions: dry Calakmul, the Highland quarries, the Yucatan salt coast, the Usumacinta, Cozumel. One purse across all of them.

There is always something on the hearth

Come back for

  • Missions

    Fifty goals in seven chapters, three live at a time. Finish one, come back and claim the cacao, Jade and rank it pays.

  • Achievements

    Twenty-four lifetime achievements in bronze, silver and gold, from your first fifty vessels to the whole Codex, each tier paying Jade.

  • Daily reward

    A seven-day streak of cacao, crates and Jade, with a banner token on day seven. Miss a day and you can mend the streak.

  • Civic rank

    Villager to Sajal and on to Kaloomte. Ranks are earned across every region and grant real powers: collect all banks at once, a fourth mission, a bonus on every rate.

  • The Codex

    Twenty-four vessels, twelve peoples of the Maya world and its neighbours and sixteen heirlooms to find, with a story for each. Completing a set pays Jade and a title.

  • Territory

    Every city starts on a small plot. Buy the next ring of unclaimed land, wait for the workers to clear it, and the city grows outward, ring by ring, in every region.

    One stone landing and 6,000 cacao. Build a landing, a storehouse and a cistern, then serve your first vessels.

  5. L5

    Great Capital

    The end of the road: a capital the whole Maya world trades through.

Screens

Built for a desktop browser at 1280 px and wider with WebGL on; a landscape tablet works, and on a phone the panels fold into a bottom bar and sheets.

Current Chrome, Edge, Firefox and Safari. Reduced-motion settings are honoured, and the effects tier steps down on slower machines.

Questions

What kind of game is this?

A calm river city builder. You start with one stone landing in the Preclassic and grow a city over weeks of short visits. Timers run on the real clock, so it keeps working while you are away.

Is it free?

Yes. Every building, region, mission and achievement can be reached with cacao and patience. Jade can also be bought with real money in the Store to skip waits; prices are shown in US dollars before you pay.

Do I need an account?

No. Your city saves in your browser. Sign in only if you want a cloud save on more than one device.

How true to history is it?

The places, trade goods, buildings and peoples are real, and the mechanics draw on Maya astronomy, mathematics, writing, water engineering and trade between about 400 BC and AD 900. Centuries are compressed for play, and many sites go by their modern names. It is a game about rivers and trade, not a full portrait of Maya society.

Are the Maya a people of the past?

No. Millions of Maya people live in Mexico, Guatemala, Belize, Honduras and El Salvador today and speak about thirty Mayan languages. Some entries in the Codex name communities that still keep these traditions. The game treats the Classic cities as one chapter of a continuing history.

Does religion appear in the game?

Temples, festivals and the Calendar are part of city life, and readings are written as the work of skilled daykeepers. No god is a character, and offerings in the game are copal, maize, cotton and work. Nothing in the game makes light of anyone's beliefs.

Does it work on a phone?

Yes. On a phone the panels become sheets over a bottom bar, and the world pans by drag and zooms by pinch. A desktop screen shows more at once.
