As the title suggests, you will have to contact the casino support staff to claim your offer in this method. Send an email or use the live chat option after registration to claim your no deposit bonus. Very few US online casinos use this system, so you will not encounter it often when playing with no deposit bonuses. No deposit bonuses usually award you with Gold Coins (GC) which are the special currency that most sweepstakes casinos use. GC don’t have any real money value, but if the no deposit bonus isn’t enough for you, you’ll always be able to go off and purchase more coins. No deposit bonuses at the best sweepstakes casinos usually also include Sweepstakes Coins (SC), which can never be bought, but can be accumulated from gameplay, and later redeemed for prizes like cash or gift vouchers.
