Delaware will allow single-game and championship betting on professional baseball, football, hockey, basketball, soccer, golf and auto racing at all three of the state's casinos.
Wagering can begin at 1:30 p.m. on Tuesday.
For now, only bets professional sports are permitted. However, college betting may be permitted in the future per USA Today.
Delaware was one of five states previously under partial exemption from the federal sports betting ban because of laws it had in place before the ban was made official in 1992. But options were limited to things like parlay bets on NFL football games.
