Idle Island – City Builder Guide

The Basics

In the game, you run a city by constructing houses, stores, and transport stations. People buy the stuff from the stores and you earn money. You need houses to let the people live in the city and transport for supplying the goods from store to apartments. So the basic game cycle is -> House -> more people -> buy stuff -> stores -> transport -> supply goods. If you don’t have enough house, you will not be able to invite more people to the city. Without growing the population, you can’t progress. So all the players need to build houses for city growth. The next thing is the store where the citizens visit and shop for items. If you have fewer stores, but more citizens, then you will not be able to get the most out of that population strength. So it’s necessary to keep the balance. Also, the more you have the population, the more cars you will need for transportation.

How many houses, stores, and cars that you can build in the city?
