The reason online casinos offer very small betting amounts before even downloading their software is so that online gamblers can test out the site, practice their strategies and compare virtual casinos. There is fierce competition going on, and online casinos are willing to bet their site is better than any other. If it means spending a few extra dollars and allowing free play, so be it. After all, they don't have the overhead expenses of land based casinos. With gambling, you are not just making extra cash but also accompany a group of new friends who make your leisure time interesting.
