When you enter the game, your city is displayed.  The upper left shows your stat, level, credibility, exp, gold, diamonds and the rice balls you have.  The bottom left shows two option - calendar and setting while the bottom right shows an arrow.  Do you notice the bottom centre part ? You can play this game anytime, it's not a fully-online game.  Partly online game by precision.  You tap the bottom centre button to reconnect.  

Here's a screenshot when you zoom out by pinching.  I guess everyone knows how to zoom in and out.  By zooming out you can see the city more clearly and also it helps you to collect money easily. 

When you press the yellow arrow button, more options appear.  Let's talk about the first option, aka a hammer.  It's for building.

Press it and you're catapult to another wonderful world, forgive my exaggeration.  Do you spot the space lucky bag ? It's the weather I'm opting for in my city.  You can buy a lot of weather for your city.  Four seasons, space, Halloween, Valentine's etc.  They are pretty and attracting.  But it will be a problem if you're still a beginner because every lucky bag (weather) costs money, some even cost you diamonds! 

You can build a lot of hotels to accommodate your tourists and grow and city.  The hotels are pretty creative and unique.  The colours are vivid and the structures are minuscule and cute.

You need to build shops to expand your city.  And again, there are loads of shops you can choose.  Bakery, restaurant, boutique etc.  They are really solid.  You can make shop sale to upgrade your shop, by upgrading it, you'll earn more.  Sometimes your shop gets dirty, you need to clean your shop to make sure your earning is at optimum.  However, cleaning your shops also require rice balls.

Next, there are myriad of minuscule decorations you can place in your city, preferably beside your shop simply because the decorations will increase the outcome of your shops.  There are also varies type of road you can choose.  

What can you do with your diamonds ? Yeah, you can buy hotels, shops and decorations, just to name a few.  Of course the outcome is more desirable.  

I have three maps as you can see, different cities in each map.  You can customise your map according to theme or weather.  Maximum up to 6 shop sales per map.

You need gold or diamond to unlock a map.
