Still, the two Native American tribes will have to wait a few weeks before they were able to accept any wagers. The official federal approval was published yesterday in the Federal Register. The agreements, which are also known as compacts, provide rules about how sports betting can be conducted in the Tulalip and Stillaguamish tribe’s casinos, as well as in entertainment venues, hotels and conference centers. On September 1st, the federal Bureau of Indian Affairs (BIA) announced that it gave its approval to the amendments that had been brought to each tribe’s gambling deal with the state. The Stillaguamish and Tulalip tribes were officially allowed to proceed with offering sports betting services in their casinos after they managed to clear a final obstacle on their way.
