Coins are a very important resource in Megapolis. They are very easy to earn! Here are a few methods of how you can do it:

1. Taxes. Build infrastructural buildings and gather taxes. Wait until you see little coin icons appear above the buildings, and then press on them. The more buildings you have, the larger your income will be, which will help you fill up your city’s Treasury.

2. Daily gifts. Come to Megapolis every day and get bonus coins as a gift.

3. Order Board. Another way to get coins is to complete orders from the Order Board, which is located at the Airport. You will need to build at least one factory in your Megapolis to start fulfilling orders.
 
4. Rewards for completing tasks. Get coins for completing tasks. Available tasks are listed on the left side of the screen. Each task description comes with information about the kind of reward you will get for completing it. Often times, the reward is coins.
5. Rewards for unlocking achievements. Get coins for unlocking new achievements. To see the full list of possible achievements, press on the trophy cup icon in the upper-right corner of the screen. There you will find all the different things you can do to unlock achievements, as well as information about what you will get once you do so. A great number of the rewards will be coins.
6. Manufacturing. Keep working on developing your manufacturing and resource gathering facilities. Build railroads, airports, and cellular towers. Grow tourism, entertainment and other industries in your city. Each of them has the potential to bring your city lots of money!

7. Sale of buildings. In case you are really strapped for cash, sell a few buildings. Make sure to keep in mind that you will get only a portion of the initial cost of the building back if you do decide to sell one. If you sell a building that you purchased for Megabucks, you will only get coins in return. You will have a chance to see the exact amount of coins you will get before you confirm the sale of the structure.

8. Purchase in store. Finally, you can always buy more coins in the in-game store. You can find out how to do so in appropriate FAQ section.

Have fun playing the game!
