Ball rack 1, for selectively setting balls 18 on a cue game table into a triangular pattern or diamond pattern, comprises a substantially equilateral triangular frame 2 having upstanding sides 4, 6, 8 defining triangular aperture 21, and at least two fixed struts 12, 14 defining generally diamond shaped aperture 23 together with two sides 4, 6. The rack may shape fifteen balls 18 in a triangular snooker pattern or nine balls 18 in a diamond pool pattern. The fixed struts may be shaped as serpentine curves (26, 28, fig. 2a), and the rack may include three fixed struts (26, 28, 36, fig. 4) such that any pair of fixed struts forms a diamond shape in conjunction with the frame sides. The height (H, fig. 1a) of the sides 4, 6, 8 may be twice as high as the diameter of the game balls 18, with the strut height being half the side height, such that the triangular ball pattern may be formed using the sides 4, 6, 8 with the struts 12, 14 passing above the balls, and the rack may be inverted to form the diamond pattern using the struts 12, 14 and the sides 4, 6. |
