Referrals are players that you invite into the game. You can do it using any of the following methods:
- Sending invitation letters to email addresses
- Placing referral links
- Placing flash banners in forums and blogs that support HTML
Every time a player that was invited by you ranks up or buys crystals for real money, you automatically receive a corresponding bonus on your account.
Click on at the top of your screen in the lobby to invite new players.
You get crystals every time any of your referrals rank up.
10% of the sum of crystals bought for real money are sent to your account (Double Crystal Card bonus is not taken into account).
