Ima ih mnogo i teško je stupiti u kontakt ili je to drugačija valuta od naše

Some no deposit bonuses do not work or activate and only deposit with a real balance to use the bonus

Alguns bônus sem depósito não funciona ou ativa e dps só com saldo real depositando pra utilizar o bonus

Hello, could you give a concrete example of where this happened and with what bonus ? 

If it was a no deposit bonus, then it seems illogical to me that you have to deposit. It might also be a good idea to ask the casino what is the matter and if there was any mistake. Have you tried that as well ? 

Let me know. 🙂
