✪ Step-by-step guide:
To get free gems in Clash of Clans:
1. In iOS Safari, go to: http://abo.io/code4u on your iPhone/iPad/iPod
Enter the invite code: CODE4U (can be lower case) to get extra points
2. Start downloading apps. After downloading each app, keep it open for at least 30 seconds - you can delete them later.
3. You'll get points for downloading these apps.
4. Exchange the points for iTunes Gift Cards
5. Use iTunes gift cards to get free gems in Clash of Clans!
http://abo.io/code4u and follow the on-screen instructions. Use the invite code for extra points: code4u
The rest of the steps is the same as iOS, use "code4u" as a code to get more points
✪ To get the gift card and exchange for gems once you have enough points:
iOS (iPhone, iPod, iPad): may vary slightly in future iOS updates:
1. On your iPhone, go to 'Appstore' app.
2. Click on 'Featured'
3. Scroll down, where you Apple ID is and tap on 'Redeem'
4. Enter the iTunes gift card code and confirm.
5. Use that cash to get free gems in clash of clans!
Android: use Google Play Store credit codes to top up the balance and spend it on gems
* Check if iTunes cards are on a list of rewards in your country!
✪ More ways to get free gems:
It is easier to earn enough points just to redeem one iTunes gift card which will be enough to get a 'Bag of Gems' (1200 free gems) and a 'Pile of Gems' (500 free gems).
You can just go for a lower iTunes gift card denomination. New apps are added regularly by Appbounty.
This is one of the quickest methods to get gems for free, without paying your own money/survey/hacking/jailbreak. Any videos claiming that you can either hack the game to get free gems - these will only allow you to play offline or just to force you to complete surveys!
Other ways to get free gems in Clash of Clans (time consuming):
Complete achievements in CoC - completing every available achievement in Clash of Clans gives a total of 6000+ gems. The achievement which gives you the most gems is a part of "Sweet Victory" achievement - you will get 450 free gems once your trophies level is 1250.
Clearing the debris in the game - gives you a few free gems at a time. Debris keep re-appearing after a certain amount of time and you can use gems for boosting your gold mine or elixir production. As a downside - you have to wait for the debris to re-appear. Nevertheless, you still get some free gems. Also, keep an eye on the gem box which contains 25 gems and pops up on occasion.
