Are they meant only for the Twitter followers to grab those giveaways as not all gamblers are following the gambling Twitter handle and some may rarely visit Twitter???
They are giving away on Twitter through these giveaway and promotional tweets but this doesn't mean it's meant for Twitter users only as you see they have huge following and many are platform gamblers also.Suppose they give free spins or codes you need to redeem it on duelbits casino only.So they are for all but only few who are lucky and active will get it.
