80 acts were pulled from the 100+ acts that were accepted by the judges in the Auditions. The Judge Cuts took place over four days; every day, 20 acts performed with only 7 moving on to the Quarterfinals.
Joining the main judging panel were four guest judges. While each regular judge was given a normal buzzer, each guest had only a Golden Buzzer which he or she could press to send an act to the live shows without further deliberation as one of the 7 acts.
