When you reach level 9, Your VIP ward opens and VIP patients will start to visit your hospital. VIP Patients are like regular patients in your Treatment Rooms, but usually give more coins if cured and leave a special VIP box. There is a catch though. VIP Patients are always in a hurry and require a quick treatment, because after 3 hours they will leave your hospital without giving you rewards. So be quick to cure them!
Whenever you cured a VIP patient, a new one will stop by after some an hour. If you did not manage to cure the VIP patient and he/she leaves, a new VIP patient will stop by after three hours.
