Our take

Three products that look alike and are regulated nothing alike.

Hard Rock Bet is a sportsbook: it sets the odds and takes the other side, and each state licenses it separately. Novig is an exchange regulated by the CFTC, where you trade contracts with other users and pay a small fee instead of the house margin. Underdog sits in between, with fantasy games under state rules and predictions on its own federally regulated exchange.

That difference decides where you can play. Hard Rock's sportsbook runs in 10 states. Novig is open to users 21+ everywhere except Arizona, Michigan and Nevada. Underdog's age limit moves from 18 to 21 depending on the state.

None of it is income. Set a budget you could lose in full, and if betting stops being fun, the 1-800-GAMBLER line is there for exactly that.

How we picked:

  • Licensed or federally regulated in the U.S.
  • Clear state and age eligibility
  • Welcome offer terms published by the operator
  • Responsible-gaming tools and helpline shown
