Battle Ages

You can get this achievement in the Medieval Age and you do not need to spend any money. If you build every building available that can be built with coins you will have 28 buildings available out of the 30 you need (this counts the two builders and one research building you get for free).

You will need two more buildings this achievement that you can either get by getting to the Renaissance Age or by using gems to build more builders and or research buildings.

This games is very generous with gems. You get them for completing research, leveling up, weekly ranking with friends, etc. I have not spent a dime on the game and had over 500 gems to add a third builder after about a week and another 400 gems a week later. After I completed all of the buildings in Medieval Age, I added a second research building that cost 250 gems and that got me the achievement. You will need 750 gems total to add one builder and one research.

These are buildings I was planning on adding anyway to make better use of my resources earned thru attacking. If you are planning on expanding this way I would recommend adding these buildings to get the achievement rather than waiting to spend 1,150,000 coins to level up to Renaissance. But if you were not going to add additional builder or research you may be better off saving your gems.

Field of Dreams

Note: I did not spend money on this game or promote spending money, you can spend money at your own will but just because it is in this solution I do not promote this game at all.
This achievement isn't nearly as difficult or time consuming as Grow your Empire (upgrade 100 buildings) but it will take some time. You must first obtain this
achievement: (Unless you use Jewels to buy 2 buildings that only cost Jewels)



Once you are in the renaissance age you must build all possible buildings (walls do not count) and the achievement will pop when you hit building #30.

How to earn a ton of free Jewels:


For those willing to spend Money to make this faster:
You can buy 3 more construction yards (5 total) which allow you to upgrade/build more buildings at the same time with a total of 3500 Jewels (500 first time, 1000 second time, 2000 third time).
