|Some of the newest incarnations of fantasy football look a lot more like gambling than intricate, outsmart-your-opponent strategy games. With players betting thousands or even tens of thousands a night, legal experts believe it's time to review the section of the 2006 federal law that was written specifically to protect fantasy sports from being banned the way online poker was. The games are pretty much unregulated, and they are exploding. They allow anyone over 18 to gamble on sports outcomes online, while traditional sports gambling is available online only in Nevada and, in some forms, in Delaware. The laws in the states take precedence over the federal law and they vary, most of them basing the legality of a game on how much of it is predicated on skill vs. chance. Last year, a federal court in Illinois dismissed a lawsuit alleging day games were games of chance.
