Six browser economies on the trading floor

Four of these games are pure markets where your rivals are other players and the numbers move because people moved them. One puts you in charge of an airline on a real map, and one hands you a cheerful hospital full of odd ailments. Each card shows the weekly time it asks and where it runs.

Sim CompaniesBest overall01
Player-market business sim

Sim Companies

A deliberately slow economy where you grow from one small building into a chain of factories, farms and stores. Every price on the exchange was set by another player, production runs on real hours, and direct contracts between companies are a craft of their own. The best balance of depth and calm in the genre.

Prosperous UniverseDeepest economy02
Space-economy sim

Prosperous Universe

A space economy where every commodity, from water to ship hulls, must be produced by a real player. You build bases on planets, run production lines, fly cargo between star systems and trade on exchanges that never close. There is no combat at all. It is enormous, demanding and unlike anything else in a browser.

VirtonomicsOne turn a day03
Daily-turn economy sim

Virtonomics

A multiplayer economy of factories, mines, farms, research centres and shops spread across more than two hundred industries. The whole world updates once a day, so every player’s decisions resolve together. You plan, submit and wait, which makes it the purest test of judgement in the genre and the kindest to a busy schedule.

Airlines Manager: TycoonBest for map lovers04
Airline tycoon

Airlines Manager: Tycoon

Run an airline across a live map of real airports: choose city pairs, size aircraft to demand and finance a fleet by negotiating with the game’s bankers. Research projects and cabin services shape each route, and alliances let you grow with teammates. Two speeds, real time and accelerated, suit very different weeks.

KapilandsMost hands-on05
Production economy

Kapilands

A long-running browser economy from upjers with more than forty production facilities and up to a hundred products. You buy raw materials, manufacture goods of varying quality and sell into a market that follows supply and demand, haggling with other players and striking contracts in chat. Busy, sociable and rewarding to tinker with.

Kapi HospitalGentlest start06
Hospital management

Kapi Hospital

A light-hearted upjers management game in which patients arrive with absurd complaints, from smelly feet to a downy beard, and need the right room and the right treatment. You hire doctors and nurses, buy equipment and grow a small clinic into a large medical centre. No market to read, just a tidy, cheerful routine.
