Abstract
A marble race toy (4) for use with a marble race game (2) of the type in which a marble (6) moves along a tortuous path. The toy alters the path of the marbles rolling through the game along a track (16) and includes a downwardly sloping first portion (10) extending from an entrance (18) and continuous with an upwardly sloping second portion (12). The toy includes a third portion (14) parallel to the second portion. The third portion includes an upper end (28) coupled to the second portion by a U-shaped track portion (34) for generally reversing the direction of the marble, and a lower end (30) which opens into the exit. An escape (36) couples the second and third ends (22, 24) of the first and second track portions to the exit to allow the marble to move through the toy, bypassing the third track portion.
