Players can set their own daily or weekly deposit limits on our platform. If anyone feels their gaming is getting out of hand, self-exclusion allows them to temporarily close their account for a set period.
399der never allows minors to participate in gaming. A strict age verification process is enforced at registration. We believe responsible gaming is the best approach for everyone in the long run.
