Delaware's legal sports wagering kicks off at 1:30 p.m. on Tuesday at the state's three casinos. The move comes just weeks after the U.S. Supreme Court struck down a 1992 federal law that had banned sports betting in states that didn't already have a law on the books, such as Nevada.

Delaware already had a partial exemption to the law and offered parlay betting — multi-game bets — on pro football.

Now, however, gamblers there will be permitted to bet on single games and championships for a variety of professional sports, including baseball, football, hockey, basketball, soccer, golf and auto racing, according to the governor's office.

The "First State" is beating its peers to to the punch on rolling out sports betting. Lawmakers in New Jersey — which had challenged the federal law banning it — are expected to consider legislation this week that would regulate such wagering.

Other states moving toward offering it include Pennsylvania, West Virginia and Mississippi.
