Bro.

If you are new to "Gambling" free money or even deposit bonuses is always having some rules T&C most of them have wagering requirements you need to fill. I'm not defending Rockepot, but almost on all casinos every bonus or free money always has T&C + Wagering you need to finish first, there also has some rules you need also deposit and wagering before withdrawing the money you get from a bonus.

No one or never casino who wants to give free money without T&C.
