Connecticut only has two casinos, with Foxwoods being one of the largest casinos in the world. The only form of online gambling is pari-mutuel pools with greyhounds and horse racing. So, Connecticut gambling laws in 2020 allow you to play at land-based Foxwoods Resort Casino in Ledyard and Mohegan Sun in Uncasville. However, sports betting and online poker sites are not allowed. It is legal to play lotteries, DFS and bet on horses via mobile apps.
