Rhode Island sports betting was legalized on June 22, 2018, so the turnaround for the Tivertonsports betting launch was very impressive. Sports betting has been a part of Twin Rivers Tiverton since nearly the beginning, and that shines through in the overall quality of experience. The casino itself only opened on August 30th, 2018, so the facility is state-of-the-art and brand new. The Twin River Tiverton Sportsbook, which is operated by William Hill, was launched on December 3rd, 2018.
