发明名称 Ball and ladder game
摘要 A tethered ball toss game is described in which a number of tethered balls arranged at both ends of a series of cords and secured to the ends of the cords by knots are tossed from a prescribed distance toward a number of horizontal bars positioned between upright supports which are retained in perpendicular angularity to the underlying support surface by bottom supports. Each of the horizontal bars are relocatable in a vertical direction along the side supports to other pre-determined points for engagement with the side supports by engaging a retractable latching member into a cooperating hole so that the bar is secured in the desired position. In this fashion the distance between the bars can be altered to vary the difficulty and skill levels of the game. Alternative embodiments of the game are also contemplated where the length of the bars is varied by changing the shape of the side supports to accommodate shortened horizontal bars. This different array of bars can be progressively shorter from bottom to top, or vice versa, or have shorter bars at the middle of the vertical distance.
