The multidimensional interchangeable modular ball game apparatus is used for building game playing skills, such as hand-to-eye and foot-to-eye coordination. The apparatus can be used for throwing, kicking or hitting any type of sports ball and can help with practicing all types of sports, as well as with early childhood development and rehabilitation. The apparatus includes a base with a stem extending from the base. Arms of different lengths are supported by the stem and may also be placed at different heights. Different geometrically shaped hoops and targets of varying sizes and colors can be made with an open or closed net. Another embodiment includes a horizontal beam stand with hoops attached to the stand.
