March Madness Underdog Betting Tips

  • Shop moneylines at multiple college basketball betting sites to get the best value.
  • Carefully monitor March Madness news, team lineups, and overall tournament progress.
  • Review previous tournament meetings between the teams if possible, otherwise look back at any regular season results.
  • Bet on underdogs using the moneyline when you’re confident they can win outright.
  • Betting big underdogs to chase your losses or break even is always a bad idea.
  • Be careful parlaying big March Madness underdogs. Single-game point spread, total, and moneyline bets are much safer.

How to Bet on March Madness Underdogs

Time needed: 3 minutes

How to Bet on March Madness Underdogs

  1. Create a new sports betting account.

    Register a new sports betting account with one of our legal college basketball betting sites and deposit money. Use your Visa card or MasterCard, or deposit with a bank transfer, or other methods like Paypal.

  2. Review moneylines for upcoming College Basketball matchups.

    Review moneylines for upcoming matchups, noting which teams are big underdogs. Sports betting sites typically begin posting moneylines 24 hours before first pitch.

  3. Note matchups with big moneyline underdogs.

    Review games with +300 or greater moneylines. Betting the moneyline gives you a chance to earn a larger than average payout.

  4. Choose your bet and place a wager.

    Choose your bet and then use the funds you deposited to place a wager. The sportsbook will pay your winnings or deduct a losing wager from your account balance after the game.
