Pool game device, system, and method

A device comprising a housing having an upper grab member having a height, diameter, cross-section, shape, and surface configured to be grabbed by a hand of a child or an adult, an actuator member at least partially enclosed within the upper grab member, wherein a portion of the actuator member protrudes upwards from a top of the upper grab member, the actuator member being operatively engaged with an upper shaft which is, in turn, operatively engaged with a lower shaft, the upper shaft and lower shaft together forming a shaft assembly, the actuator member being configured to move up and down within the upper grab member so as to vertically move the shaft assembly, the device further comprising a spring member within the housing arranged and adapted to urge the actuator member in an upward direction, a lower housing, a flexible disk shaped member within the lower housing, the flexible disk shaped member secured to the lower housing, a center of the flexible disk shaped member being movable by the actuator member through operative engagement of the center of the flexible disk shaped member with the shaft assembly, the device further comprising a release button accessible from a side of the device and extending at another end horizontally transversely into the housing and being urged outwardly by a release button spring when the actuator member is depressed, the release button having a protrusion configured to provide locking contact with the shaft assembly in such a way as to lock the actuator member in a down position against resistance of the spring member, thereby placing the device in prime mode wherein the flexible disk shaped member is relatively flat, the release button, when pressed inward against resistance of the release button spring, being arranged to release the actuator member by moving the protrusion out of locking contact with the shaft assembly, thereby allowing the actuator member and the center of the flexible disk shaped member to move in an upward direction to place the device in engaged mode wherein the center of the flexible disk shaped member is raised relative to its position when the device is in prime mode, the device adapted to cause the flexible disk member to engage a flat surface of a swimming pool by suction when the flexible disk shaped member is pressed against the flat surface when the device is in prime mode and then moved to engaged mode.
