While daily fantasy games (DraftKings, FanDuel and others like them) may have gotten a special exemption for online betting from Congress in 2006, today the Nevada Gaming Control Board decided they do constitute gambling, and shut down their operations (PDF) in the state. Daily fantasy games were already banned totally in some states (Arizona, Iowa, Louisiana, Montana and Washington), but the home of Las Vegas casino gaming is another matter entirely. This follows a tough couple of weeks for the multi-billion dollar industry which has come under scrutiny because so many employees of the two largest competing sites were playing and winning on each other's sites, with questions over whether they could possibly use insider information to get an edge. Both sites have since banned their employees from playing, but the controversy has not gone away.
