The state never progressed under the 2017 law, due to tribal concerns and expansion problems.
In the new bill, legislators could look to tackle the standing prohibition and develop a clear direction on the future of mobile sports betting, although the place holder bill, S 665, currently provides little insight.
The bill also follows a failed effort by Governor Dannel Malloy from last year.
One of the more pressing issues concerning sports betting in Connecticut remains the dispute on exclusivity between state government and tribal casinos.
The Mohegan and Mashantucket Pequot tribes allege legalising sports betting would violate their state agreement.
The tribes say sports betting falls under their assigned rights within the state, but Connecticut attorney general George Jepsen disagrees.
In April, Jepsen wrote a letter to highlight sports betting as a Class III game under federal law, claiming is not an authorised game under either of the respective state agreements.
The proposed bill has been referred to the Joint Committee on Public Safety and Security.
