Occasionally there are offers or special gifts sent out to players. If you are an active player that has had your account for at least one day prior to the offer being sent out, you should be able to claim these.
If you do not see this gift, it may be because the account was not active recently, was created after the offer began, or the inventory is currently full. Please feel free to reach out to support with a ticket explaining which offers you are looking for and we will try our best to assist.
