The 2025 March Madness tournament has reached the Sweet Sixteen round, and betting odds are still favorable to those looking to place bets.
Every year, the NCAAB season showdown starts with 64 teams playing for a chance to win the college basketball national championship. Eventually, the competition dwindles to two teams playing for the right to call themselves NCAA Champions.
Future odds indicate who is favored to win the tournament, while game lines offer matchup odds. Below, we will discuss game lines and futures for the 2025 NCAAB postseason and the legal ways to bet on the competitions.
Sweet Sixteen Game Lines
One of the most popular ways to bet on college basketball is with game lines. Game line odds feature spread, totals, and money line odds, giving bettors three ways to bet on a matchup.
The Sweet Sixteen round will begin on Thursday, March 27th, and conclude the following day. Four games are scheduled for both Thursday and Friday. Elite 8 games will occur on Saturday, March 29th, and Sunday, March 30th, before the final four and national championship, which is scheduled for next week.
