Naijapolis

E kaabo Nnọọ Barka da zuwa Akwaaba

Build your world,
one street at a time.

A cozy city builder you play on your phone. Start with a patch of sand and make it your own: lay the roads, light the lamps, open the market, and watch a neighbourhood come alive around you.

A sunny street in Naijapolis: market stalls under orange umbrellas, a yellow danfo bus, an okada rider, bunting strung between poles, and a flag over a yellow house. The same street at night: street lamps glowing, the danfo still rolling, bunting overhead.

Naijapolis is a slow, friendly city builder. There is no rush and no enemy. You decide what your neighbourhood looks like, how it sounds, and who looks after it.

Your neighbourhood,
on a little map.

Every street starts empty. Give your city its own name, then tap a place on the map to see what lives there and what it asks of you.

Market

Stalls and kiosks bring money, noise and life to a street. Give the traders a good spot and a market day will do the rest.

A day in Naijapolis

Morning light on the market. Golden hour on the main road. Lamps and generators humming after dark. Every hour has its own mood.

Golden hour on the main road: a danfo bus, an okada, a tuk-tuk, a mosque in the distance and a yellow house behind a white wall.

The street at night with glowing lamps and bunting.
The lamps come on
The market stalls under orange and dark umbrellas, with fruit on the tables.
Fruit, umbrellas and gossip

Made for your phone.

Your plot is waiting.

It takes about a minute to lay your first road.

Behind the scenes

How a whole city fits in one page

A nine-part engineering series on how Naijapolis is built: the one-file build, a kernel you can test, the simulation, the graphics, the generative music, how cities are shared safely, how it stays up, and how trees, flowers and rivers are grown, and how the town deals with its rubbish. With diagrams, and things to try yourself.
