For approximately a thousand years, maybe more, people have been testing their luck at various games of chance, or gambling. For example In ancient Rome, the locals bet on many professional sports...such as the most unbelievable sporting event EVER...the gladiator fights that took place within the Coliseum. In those days, events like that were several of the best gambling spectacles, and in most cases were for the sole entertainment of the Kings and/or Queens of Europe during the middle ages. Royalty were known to be serious gamblers, and actually set the tone for that sort of event... Actually, there are lots of books that cover the topic telling the story that many of the Kings and/or Queens were seriously addicted to gambling, and Unisinucartagena website that many nearly bankrupted their very own countries because of the addiction.
