A regular player can become a Supporter if he meets one of the following criteria:
1. Has earned at least 2,500 Gems through Tapjoy offers. But in the past that was 1,000 gems. The change was due to the update which nearly doubled the value given by Tapjoy offers.
2. Made any In-App Purchase.
As a reward, this feature will give you the following:
1. New skin colours (Red, Purple, Dark Green, Blue, White, Light Green). These were added in Day Two of Player Appreciation Week.
The 6 New Colors for the Supporter
2. The ability to broadcast to other people (which you can also get by being Level 20).
3. The Recycle Tool that lets you convert items or clothing into a certain amount of Gems.
4. The Supporter Achievement.
