The present disclosure provides for the conditioning of a bowling ball coverstock by a controlled local environment, wherein the local environment has a relative humidity greater than an ambient relative humidity such that an evaporation rate in the local environment is less than a condensation rate in the local environment. A container, which can include a vapor barrier layer encompasses the bowling ball and a humidity source to provide the sufficient humidity within the container for a treatment period sufficient to reduce a Shore D hardness of the coverstock.

Training balls are presented including: a solid sphere defining a first hemisphere having a first surface and a second hemisphere having a second surface; a tactile feature positioned along the first surface and substantially centered with the first hemisphere, where the tactile feature includes: a center portion having a closed geometric shape; and a continuous grooved border encompassing the center portion; a first grooved feature positioned along the second surface, where the first grooved feature includes a first body segment; a second grooved feature positioned along the second surface, where the second grooved feature includes a second body segment, where the first body segment and the second body segment are substantially parallel, and where the first grooved feature and the second grooved feature are substantially centered with and solely upon the second hemisphere along the second surface.

A bowling ball can have an inner core layer that is shaped, constructed, and/or configured to provide the bowling ball with one or more prescribed properties or characteristics, and a cover stock layer comprising a liquid curable material received about the inner core layer. The bowling ball further has a riser pin feature that is at least partially defined by a passage extending through at least the cover stock layer and in which a filler material is received. The riser pin feature can be located in an opposite hemisphere of the bowling ball from a hemisphere including the true center of gravity and a marked heavy spot of the bowling ball and can be arranged within about 1 inch of an end of the Low Radius of Gyration Axis of the bowling ball.

A core of bowling ball includes a rotating disk, a center bearing, a finger hole bar and a plurality of joint pole. The center bearing is disposed on the center of the rotating disk. The finger hole bar is linked to the center bearing. The joint poles are passed through the center bearing and disposed horizontally with the finger hole bar.

Embodiments of this disclosure are related to methods and systems associated with a game. The gaming system may be configured to allow a thrower to throw an object, and store tokens associated with the game within the object. This may allow for players of the game to readily and efficiently tabulate the score of a game. Embodiments may include a throwing object and tokens.

A fog emitting bowling system for emitting fog from a bowling ball includes a bowling that is manipulated during game play of bowling. A fog unit is positioned within the bowling ball. The fog unit emits fog outwardly from the bowling ball when the bowling ball reaches a trigger velocity. In this way the fog unit enhances an appearance of the bowling ball.

A device for pushing a bowling ball with finger holes. The device includes a pole with a grip end and an opposite distal end. A push direction is defined from the grip end to the distal end and a withdrawal direction is defined from the distal end to the grip end. A plurality of fingers is configured to be received within the finger holes of the bowling ball, each having a base end and an opposite tip end. A pole coupler couples the fingers to the distal end of the pole such that when the fingers are received in finger holes, each finger is translationally movable relative to the finger holes only in the withdrawal direction. The device is configured to push the bowling ball by positioning the fingers into the finger holes, pushing the pole in the push direction, and retracting the pole in the withdrawal direction.

A bowling ball with selected performance characteristics can include an inner core, an outer core and a cover stock layer. The inner core can be configured with a first zone that can extend substantially along a first axis defined through the inner core; a second zone that can be located between the first axis and a second axis that extends substantially perpendicular to the first axis; and a third zone can be located adjacent the second axis. A plurality of finger holes can be formed through the cover stock layer and can be selectively located within at least one of the first, second, or third zone selected based on a target RG value.
