Blacklisted Online Casinos

Sites have to meet our strict guidelines to pass our gambling site evaluation process. Unfortunately, that means not every online casino review is favorable.
Blacklisted sites demonstrate high levels of incompetence or outright fraud. If they do not pay winnings, they are at the top of our blacklist.
Reviews of Gambling Sites That Have Closed
The following sites are closed and no longer accept new registrants. Before they closed, these sites were rogue—another great reason to read the reviews for online casinos before depositing and playing for real money.
