ABSTRACT:
A game apparatus with multiple playing modes includes a base unit, a plank support mounted uprightly on the base unit, and an elongated plank unit. The plank support includes a pair of parallel upright plates, a balancing seat which extends between top ends of the upright plates and which has two ends mounted rotatably on the upright plates, a cylindrical support rod which extends between the upright plates below the balancing seat and which has two ends mounted rotatably on the upright plates, and a positioning beam which extends between the upright plates and which is spaced vertically from the support rod so as to form a clearance therewith. The plank unit is mounted to the plank support selectively in a first position, wherein the plank unit has an intermediate portion which is mounted removably on the balancing seat to permit reciprocating pivoting movement of the plank unit, and a second position, wherein the plank unit extends movably and removably through the clearance such that the plank unit is supported by the support rod to permit alternating forward and rearward sliding movement of the plank unit relative to the plank support.
