    • Embodiments of play systems having multiple curved structural members are disclosed. Play systems illustratively include a first quarter of an ellipse, a second quarter of an ellipse, a third quarter of an ellipse, and a fourth quarter of an ellipse. Each ellipse quarter has first and second ends. The first, the second, the third, and the fourth ellipse quarters are oriented approximately vertically relative to a surface such that the first ends of the ellipse quarters contact the surface and the second ends of the ellipse quarters are above the surface. The first ends of the ellipse quarters are optionally spaced further apart from each other than the second ends of the ellipse quarters.
    • 公开了具有多个弯曲结构构件的游戏系统的实施例。 播放系统示例性地包括椭圆的第一四分之一,椭圆的第二四分之一,椭圆的第三四分之一和椭圆的第四四分之一。 每个椭圆四分之一具有第一和第二端。 第一,第二,第三和第四椭圆形区域相对于表面大致垂直定向,使得椭圆的第一端四分之一接触表面,并且椭圆四分之一的第二端在表面之上。 椭圆形槽的第一端部可选地间隔开,彼此比椭圆形槽的第二端部分开。
