More about the offer conditions
If your account meets the offers' conditions, but you have 100 or more Kredits on your account, you will not be able to get a bonus.
You can get the bonus only if you top up on the special page and only for a fixed amount, participating in the promotion. You can find more information in the "News" section or the official website's top-up page.
During the offer, you can get the gift for only one set of Kredits because, after its purchase, your account no longer meets the offer's conditions.
Purchase of special sets on the top-up page is counting as a top-up.
Bonus Kredits can be used on the Marketplace or in-game. You can also spend them to change your character's or a clan's name.
When paying for a gift to a friend, a bonus is added to the entire payment amount. Meanwhile, bonus Kredits are not counted towards the gift payment — those Kredits are immediately transferred to the game (at the moment of registration of the payment). If the amount of payment exceeds the value of the gift, the remaining non-gift credits will also transfer to the game.
