You might initially look at the speed up button in the center of the bottom menu of the main game screen, and wonder what it’s for. It looks like you’re supposed to tap it and watch an advertisement video in order to triple the speed of things, but that’s not how it works. Instead, hold your finger down on the button and everything will go at triple the speed.
That means that all of the rent you collect, will come at triple the speed. All of the customers that are served at your business facilities, will be served at triple the speed. Construction of apartments and other facilities will not happen at triple speed, but this button is a way to kill time while everything is being built.
Eventually, the triple speed bar will run out, and you will be prompted to watch an advertisement video in order to refill the bar immediately. You can choose to do this, or you can simply choose to let the bar refill by itself over time. This is the more convenient choice to make if you plan to be offline for a while after you run the triple speed bar out.
When you level your community prosperity up to level 12, you will be able to unlock the Sleepless City. This is an apartment in an entirely new city, and you will be able to build more units, have more furniture, completely different types of tenants, and make more money as a result. Your new city and your old city will be able to earn you money at the same time, in fact.
Right now, there are very few things that you can use diamonds for. You can use them to purchase an ad-free ticket, which will allow you to earn advertisement video bonuses without actually having to watch the video in order to get them. You can also use them to speed up construction on apartments and other facilities that take time to build.
What this means is that while diamonds are nice to have, they are not completely necessary, and you can beat the game without ever having to purchase diamonds with real-life money. You may even find it difficult to spend all of the diamonds that you earn for free, especially if you are used to letting construction finish by itself.
To check your community prosperity level, tap on the star bar in the top center portion of the screen. This will not only show you what your current community prosperity level is, but it will also show you what you have to do in order to meet the requirements of the next upgrade level. Typically, you’re going to have to complete a certain number of achievements, as well as build the required number of apartments and the right type of apartments.
The best quality of life option that this game has, and one that might not be readily apparent, is the long shot option, which, when enabled, allows you to zoom much farther out for a more generalized view of your complex. Simply go to the settings menu and enable longshot. This can apparently make older phone and tablet models laggy, but it’s worth testing out, especially if you have a newer model phone or tablet, so that you can see what’s going on easier.
Go to your stats area to see every relevant statistic, including how much rent you make per apartment, how much income do you make from businesses, and how much money you have to spend in order to retain employees for the businesses. It’s easy to accidentally let businesses become money losers, so be sure to upgrade them, so that you are turning a profit.
