Sport wagering is allowable based on your physical location at the time you place a wager. If you are visiting a state where sport betting is legal, you can place wagers while you are physically located in that state.
Once you leave the state, you will no longer be able to place wagers. Any winnings from wagers made while placed in a state where sports wagering is allowable will be automatically credited to your wagering account. You may access your account and withdraw regardless of where you are physically located.
