Abstract: A game playable by one or more players in which the level of skill necessary for success may be selectively varied. The game a disk-shaped piece for each of the players, a fortress structure which may serve as a target depending upon player strategy, a plurality of cup-shaped traps disposed around the fortress for blocking or confining pieces, and a plurality of magnetic parasites for affecting travel of pieces moving in close proximity thereto. The fortress is preferably in the form of a truncated cone of polygonal cross section, and it includes an upper, generally planar safe area adapted to receive pieces. Nubs provided around the safe area circumference may be oriented as desired to vary the level of difficulty by rotating the fortress. The difficulty level is further responsive to variations in fortress height, deployment of additional nubs, and optional use of a fence. Strategy involves wounding of opposing players by contacting their pieces with one's own.
