Silicon City is a Retro Building Game for a Modern World

Retro city building is back! As mayor, build your city block by block. Manage your citizens (silizens) with the help of deep statistics and analytics and get re-elected!

Retro city building is back!

Silicon City is a tribute to the good ol’ city builders from the ’90s. It revisits classic game mechanics such as grid-based playground with procedural development, different types of construction (residential area, public service building, shops and offices, parks, and cultural areas) the organization of road traffic, and managing the evolution of citizens.

You’re in charge!

As the newly-elected mayor, you’ll start from scratch. Transform an empty piece of land into a concrete jungle, welcoming thousands of citizens.

Build residential areas for future electors to move in. Provide them with electricity, entertainment, and jobs. Monitor their financial situation to tweak and polish your urban layout.

Don’t take it easy

You must be re-elected! Citizens are counting on you. They will spend their days between work, entertainment, and social activities. Provide them a variety of schools and jobs to help them to boost their skills. Meet their demands to grow your followers for the next elections.

Planning is everything

Get ready to face your worst enemy: traffic jams. Thanks to our own specific technology, you’ll get a better understanding of how to optimize the navigation of your citizens.

It’s essential to prevent them from losing their jobs, because they have been trapped in the morning rush hour, and on top of that it will cause less pollution. Also, don’t let them drive for hours to get basic groceries. They’ll be grateful.
