One toilet. An entire city. Everybody needs to go.

Welcome to a city with one toilet. Not one per district. One for everyone. The population is growing, the queue is getting longer, and you’re the person expected to make it work.

Build an isometric city of homes, workplaces and roads. Earn more as your city grows, but remember: every new resident is also another potential customer at the only door that matters.

Build the city. Then manage the queue.

Place buildings, connect districts and plan how people reach the toilet. Draw the queue's route yourself, add barriers, benches and shelters, and keep sanitation trucks moving through the streets.

A new neighbourhood means new income. It also means more people turning up at exactly the wrong moment. Morning and evening rush hours won't organize themselves.

Paper in. Waste out. Please don’t let it clog.

Every visit uses toilet paper and fills the waste tank. Set up production and deliveries of paper, spare parts, chemicals and medicine. Upgrade the toilet, schedule waste collection and keep the streets clean.

Pipes get blocked. Vehicles break down. Neglected neighbourhoods get filthy, and disease can spread. When several things fail at once, the queue will let you know how unhappy it is.

The residents have lives. And complaints.

Workers, office staff, children, retirees and tourists have different needs and budgets. They work, grow older and move around. If you expand faster than you build housing, newcomers may end up in a tent camp.

Frustration can turn into strikes. Negotiate with workers, respond to city events and decide which demands you can actually afford. The local newspaper won't miss a chance to comment on your decisions.

Even elections can’t shorten the line.

Research new sanitation, engineering and logistics technologies. Balance investment, public trust and political pressure as parties compete for influence and elections reshape the city.

Build freely in sandbox mode or take on scenarios with specific goals. Save manually or rely on autosave, then return to whatever disaster was waiting outside the door.
