The ball game comprises a pair of inclined and generally parallel upper and lower boards. These two boards are spaced apart from each other to define an interspace between the lower face of the upper board and the upper face of the lower board. The upper board has a plurality of openings therein; each opening has a contour on which is positioned a target ball of which a lower portion protrudes from the above mentioned lower face in the interspace. A third, generally horizontal board is connected to the lower board and enables players to throw a shooting ball in the interspace to hit the protruding ball portions. The hit balls are ejected from their respective openings to score points.

Why it's free to use
- Filed December 6, 1989 and granted December 10, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 6, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 6, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
