GOLF BALL

Provided is a golf ball that is suitable for golf players who can achieve a sufficiently high trajectory due to initial elements and is also suitable for golf players who cannot achieve a sufficiently high trajectory due to initial elements. The golf ball has a core, a cover, and a paint layer. The golf ball has a variable dimple on a surface thereof. The cover has a hole. A space is formed by the hole. The cover and the paint layer are not joined at a location directly below the dimple. A space is formed between the cover and the paint layer. The volume of the space varies due to a centrifugal force caused by backspin.
