Animal Hospital on Roblox does not seem to have a fixed number of “rounds” in the usual sense. Instead, each shift gives you a set number of patients for the day, and the challenge is that anomalies appear in a randomized way during that shift.

So the closest accurate answer is:

  • Shifts are the main structure , not rounds.
  • Each shift has a set patient count.
  • Anomalies can appear randomly during play, so the length of each run can feel different.

If you meant a different Roblox game mode or a specific guide that uses “rounds,” the number may depend on that version.
