A method for operating a virtual golf device comprising:

• a step of calculating a trajectory of a real golf ball when a user hits the real golf ball;
• and
• a step of displaying a virtual golf ball corresponding to the real golf ball hit by the user and moving according to the calculated trajectory in a virtual golf course,
• wherein the user can select one play mode of a first mode and a second mode, there are a plurality of users, an order of hitting the real golf ball between the plurality of users in the first mode depends on a location of each user's virtual golf ball in the virtual golf course, and an order of hitting the real golf ball between the plurality of users in the second mode does not depend on the location of each user's virtual golf ball in the virtual golf course.
