Sandburg City brings the free-play feeling of a sandbox to the screen. Children steer diggers, cranes and trucks, clear building sites and grow their own city step by step – alone or together with friends.
Big machines. Your own city. Built together.

A toy digger, a few stones and a good idea – in a sandbox, a whole city could grow from that. We wanted to bring exactly that feeling to the screen: a game where children turn their own ideas into reality, try things out and create something together with others. The focus isn't on competition, but on building together – with no time pressure at all.

Children clear building sites, deliver materials and steer diggers, cranes and trucks. At the harbour, a container ship brings new raw materials that get unloaded with a big crane. The more they build, the more buildings unlock – some open up new ways to play, like the helicopter pad: once it's finished, children can explore the island from above.

Sandburg City can be played alone or together with friends: using a simple game code, children invite each other into their cities and keep building together – the app deliberately does without chat or camera features. The game world is open: there's no prescribed path, children build, drive and explore the island at their own pace. The app was developed by the Cologne-based studio Ahoiii Entertainment, which has made games around its character Fiete since 2014.

Children decide for themselves what to build next and develop their own ideas of what their city should look like. The city keeps growing with every project and can always be changed again.
In multiplayer mode, children work towards a shared goal: while one prepares a building site, another delivers materials. They practise dividing tasks and coordinating with each other, instead of competing against one another.
Diggers, cranes and trucks need to be steered precisely – across uneven ground, around obstacles, right up to the building site. This trains hand-eye coordination and spatial awareness.
With no fixed path and no time pressure, children decide for themselves what to explore or build next. They learn to pursue their own projects and stick with them until a building is finished.
