Strategy guide and FAQ
buyworld.app looks simple: tap a real building, buy it, collect rent. But the players at the top of the rankings think about where they buy, when they sell and who they team up with. This guide collects what experienced players have learned, from your first purchase to running a global network of airports and ports.
Your first hour
Buy close to home, but not too big
Your starting coins buy a modest building. A small house or shop in a neighbourhood you know is a good first pick: you will recognise the streets, and you can check on it every time you open the game. Avoid spending everything on one big building straight away. Two smaller buildings earn about as much rent and leave you room to react when a bargain shows up in the auction house.
Read the building panel
Every building's panel shows its price, its rent per hour, its owner and its condition. Condition depends on how well buildings are built in that country and how often it has been renovated. A run-down building is cheap to buy, and renovating it often pays back faster than buying another one: the panel tells you which is the better deal.
Collect the free coins
The hourly chest, the daily reward card and the quests are the fastest way to grow early on. Open the chest whenever it's ready, and keep your daily streak going: the seventh day gives a much bigger chest.
Earning more rent
Rent is counted every second and shown next to your cash. Three things raise it:
- Size and location. Bigger buildings in valuable areas earn more. City centres, waterfronts and famous landmarks pay the most.
- Upgrades. Each of the five renovation levels multiplies the building's rent. Upgrading also adds value to the buildings around it, so a street of upgraded buildings is worth more than the sum of its parts.
- Tenants. Tenants sometimes ask for something, such as a repair or a quiet night. Answering well can boost the rent for a while; ignoring them can cut it.
Owning many buildings comes with administrative costs that grow with your portfolio. Past a certain size, a cheap building can cost more to manage than it earns. Check your money charts: if costs climb faster than rent, sell your weakest buildings to the bank or at auction and buy fewer, better ones.
Buying and selling well
Watch the market cycle
Prices move with a market index that rises and falls over the day. The newspaper reports big sales and world events, which can push prices in a city up or down. Buying when the index is low and selling when it is high is the simplest way to profit from trading.
Use the auction house
The auction house lists every building for sale. Filters show bargains (priced under their value), auctions about to end, and lots nobody has bid on yet. Lots with no bids often end cheap. If you are outbid, you get your coins back straight away and a message tells you, so you can bid again.
Make offers
You can offer to buy a building another player owns, even if it isn't for sale. Fair offers are often accepted, especially from players who haven't visited in a while. If your offer is turned down, try again later with a better price.
Airports, ports and spaceports
Transport hubs are bought whole and work differently from buildings. Once you own an airport or a port, open trade routes with other players' hubs. Planes and ships then travel the route on the map at real speed and pay both owners when they arrive. Long routes between busy hubs pay the most. Ships through the Suez and Panama canals pay a toll to the mayors there, so owning the right city can earn from everyone else's trade.
Spaceports launch satellites that pay every hour while in orbit, and probes to the Moon, Mars and beyond. Each player can own up to five airports, five ports and one spaceport, so choose them carefully.
Politics and coalitions
The player who owns the most floor space in a city becomes its mayor at the daily election, held at midnight Paris time. The biggest owner in a country becomes its leader. Mayors earn from activity in their city, and the title shows on their profile.
Coalitions let players pool their strength. Members share part of their rent with each other, appear together in the rankings and can coordinate who buys where. A coalition holding most of a city can keep the mayor's seat for a long time.
Style, badges and chat
Once you're settled, make your buildings and profile your own. Skins repaint a whole building, from a brick townhouse to a glowing neon tower, and rooftop items such as a hot tub, a statue or a hovering UFO sit on top. Your profile can wear a banner, a frame around your picture and a coloured name. Each item is bought once with coins and everyone sees it on the map or your profile.
Badges reward everything you do: day streaks, net worth, number of buildings, rent, landmarks, renovations, auctions, politics, friends, style and time played. Each theme is a branch of badges that get harder as you go, and your profile shows how close you are to the next one.
To talk to other players, open their profile and tap Message. Messages are built from ready-made blocks, like "I will buy your building soon!", so chat stays friendly and everyone reads it in their own language.
Frequently asked questions
Is buyworld.app free?
Yes. The game is free to play in any modern browser on a computer or phone, and ads help pay for the servers. You can buy coin packs to go faster, but everything in the game can be earned by playing.
Are the buildings real?
The buildings and land are real places from OpenStreetMap, the free map of the world. Owning them in the game is just for fun: coins and properties have no real-world value and give no rights over the real places.
Can I buy any building?
Almost. Places of worship, Vatican City and Lourdes can't be bought, and a few landmarks are priceless. Everything else, from a garden shed to a skyscraper, is for sale until someone else owns it.
What happens if I stop playing?
Your buildings keep earning rent while you are away. After a long time without visiting, your properties go back on the market so active players can buy them. Every visit pushes that date back, and your profile shows when it is.
How do I become mayor?
Own the most floor space in a city at the daily election. Tall buildings and large plots count the most, so a few big buildings can beat many small ones.
Can I play with friends?
Yes. Share your profile link, join the same coalition and trade buildings with each other. Inviting a friend who starts playing also earns you a reward.
Which languages are available?
More than 30, including English, French, Spanish, Portuguese, German, Chinese, Japanese, Russian, Arabic and Hindi. Pick yours from the language menu.
I found a bug or a bad ad. What should I do?
