All tournament games have Higher/Lower markets. Create an entry by selecting higher or lower on any of the following totals on Thursday:

  • Chucky Hepburn (LOU): 16.5 points
  • Ryan Kalkbrenner (CREI): 30.5 points + rebounds + assists
  • Braden Smith (PUR): 7.5 assists
  • Steven Crowl (WIS): 5.5 rebounds
  • LJ Cryer (HOU): 14.5 points
  • Zakai Zeigler (TENN): 1.5 three-pointers
  • Kadary Richmond (SJU): 30.5 points + rebounds + assists

There are two different ways to create an entry. A standard entry of 2+ picks will result in the largest potential winnings, but you can choose to flex an entry with 3+ picks and still receive some winnings if one leg doesn’t hit.
