"Pokemon Go players unravel the secret behind Gym detail"

Pokemon Go players have recently discovered that the size of a Gym in the game reflects its difficulty level. The height of the Gym is a representation of the total sum of Combat Power (CP) of all the Pokemon defending it, with larger Gyms indicating stronger defenses. This design choice, which was previously unnoticed due to glitches, provides players with a visual shorthand to determine the strength of a Gym before engaging in battles.
