The server is always right
Every calculation involving money happens and is validated on the server. The client is a display : it never decides a price or a balance. That is what makes cheating pointless.
The studio
Small team, big systems.
Ludopia is an independent studio and publisher. We make browser games that borrow their rules from the real world — a market that genuinely reacts to supply and demand, a city that is really built — and that hold up on the day a lot of people show up at once.
What we build
Games that teach something true
A stock market game could settle for a line that goes up at random. Ours computes a price from the real net flow of players, damped, pulled back towards a fundamental value, capped at every quote — because that mechanism is what we want people to understand, and you only understand what resists you.
Same logic on the city side : in Villopia, a street that no longer serves anyone is a genuine planning problem, not scenery. Our worlds share a suffix, a platform, and that obsession with rules that stand up.

Our method
Six rules that decide for us
They live in the repositories, not on a poster. When a decision is hard, one of them settles it.
Measure before announcing
A feature is only « done » once a probe proves it in production. Nine junctions out of nine equipped, not « the signs work better now ».
One colour, one meaning
Gold for production, cyan for gems, coral for urgency, purple for prestige. A new element joins an existing domain ; it does not invent its own hue.
Nothing changes instantly
150 ms for a micro-motion, 250 for a panel, 400 for a celebration. A button physically sinks ; it does not merely change shade.
One rule, one copy
Two implementations of the same rule always end up diverging. When we clean a road network, we call the existing rule tile by tile rather than writing a variant.
Premium never buys a ranking
It speeds things up and personalises, never someone else's place. And a parental cap applies before the payment, not after.
Milestones
What happened recently
The studio ships continuously. Here are the steps that mattered these past few days — the detail lives in the news.
Villopia — orphan tarmac no longer freezes land
The road network drew itself on every placement and never retracted : every street that became useless froze land for good. A single action now gives those tiles back, without ever landlocking a building or cutting the network in two.
Tradopia can tell when it is broken
An outage had been found by a player before the server noticed. The dashboard now shows a Health section : errors in the last hour, rate-limit refusals, server failures — a bounded log with no personal data whatsoever.
Card payments open on Tradopia
Gem purchases through Stripe Checkout : no card number ever touches our servers. The monthly Parent Area cap is checked before the trip to Stripe even starts, and a refund removes the matching gems.
TradiKids becomes Tradopia
The game joins the family of -opia worlds and takes the tradopia.app domain. The audience widens : 8 to 99 years old, with the interface of a real trading app rather than a childish skin.
Equipia enters design
The third world. Genetics, training, a competition calendar : we settle the economy before drawing the first horse.
