Abstract: A hockey game for use with a ball or disk including a planar deck, a pair of perimeter side walls along respective opposed long side edges of the deck, and a pair of perimeter end walls along respective opposed short end edges of the deck. Each end wall has a goal opening therein extending down to the deck surface. A plurality of substantially parallel spaced apart blocking walls extend across the deck from one perimeter side wall to the other. Each blocking wall has openings therein extending down to the deck surface and being sufficiently high and wide to permit passage therethrough of the ball or disk. Selected openings are aligned along substantially parallel lines of sight from one perimeter end wall to the other with the width of the openings in the blocking walls gradually decreasing from the center of the deck towards either perimeter end wall.
