General
- All promotions pay in virtual coins, gems or virtual items, none of which have cash value.
- One account per person. Rewards collected with several accounts, bots or bugs are void and may be removed.
- We may change or end a promotion at any time; rewards already credited stay credited unless obtained by abuse.
Promo codes
Each promo code can be used once per account, from the Promo code button in the menu. A code adds the stated amount of demo coins to your balance.
First top-up bonus
Your first demo top-up gets an extra 10 % on top of the amount you choose. Later top-ups get no bonus. See Payments.
Daily case and EXP cases
The daily case can be opened for free once every 24 hours. EXP cases unlock as you reach the level shown on each case, and each can then be opened for free once every 24 hours. See EXP cases.
Piggy bank
2 % of every coin you spend on paid cases and battles is saved in your piggy bank. You can crack it and move the savings to your balance on the Piggy bank page, subject to the minimum and waiting time shown there.
Affiliate program
Players who sign up with your referral code are linked to your account. You earn 1 % of the coins they spend, which you can claim on the Affiliate page. Referring yourself or your own extra accounts is not allowed.
Dragon pass and levels
Spending coins earns experience. Your level and Dragon pass tier follow your total experience; each pass tier's reward can be claimed once on the Dragon pass page.
Dragon Festival
During the event, every whole coin you spend earns one gem. Event cases are opened with gems and are available until 30 November 2026. Unused gems stay on your account but event cases can't be opened after the event ends. See the event page.
