support@coinroyale.comYes, without any doubt Coinroyale is one of the safest casinos out there and it has been in the market for many years, if I'm not wrong then this announcement thread was first posted in 4th quarter of 2013 and if we keep that in mind then this casino is more than 10 years old and it has been doing well throughout all those years. Only the reputed casinos can exist in such competitive market for so long, and when it comes to marketing then the casino still have a signature campaign on this forum and it regularly announce contests for the members of the forum.
