Abstract
Abstract A game device is disclosed, suitable for play by two or four persons representing two opposing sides, comprising a ''''board'''' having interconnected sets of conduits, and projectiles normally disposed at opposite ends of one of the sets capable of being individually released and propelled through their conduits by selectively applied fluid pressure. The opposing sides control the release of their projectiles and the flow of fluid in conduits in one direction, the object of the game being for one side to drive its projectiles from its end of the conduits to its opponent''s end, against a defense mounted by its opponent.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
84 words
Game apparatus comprising intersecting sets of generally horizontally disposed transparent conduits, selectively operable fluid pressure means associated with individual conduits to selectively generate fluid flow in the conduit toward one or the other of the ends thereof, a selectively releasable projectile normally disposed at each opposite end of the conduits of one set, and means associated with the conduits of said one set for effecting release of a projectile for propulsion by said fluid pressure means toward the other opposite end of the conduit.
Claim 2
Dependent Claim
84 words
Game apparatus comprising intersecting sets of generally horizontally disposed transparent conduits, selectively operable fluid pressure means associated with individual conduits to selectively generate fluid flow in the conduit toward one or the other of the ends thereof, a selectively releasable projectile normally disposed at each opposite end of the conduits of one set, and means associated with the conduits of said one set for effecting release of a projectile for propulsion by said fluid pressure means toward the other opposite end of the conduit.
Claim 3
Dependent Claim
54 words
Game apparatus in accordance with claim 1, wherein said fluid pressure means comprises fluid conducting means coupled to respective opposite ends of said conduits, and selectively operable valve means interposed between said fluid conducting means and said conduits, operation of a valve means placing said fluid conducting means in fluid communication with a conduit.
Claim 4
Dependent Claim
18 words
Game apparatus in accordance with claim 2, wherein said fluid pressure means comprises a source of air pressure.
Claim 5
Dependent Claim
35 words
Game apparatus in accordance with claim 2, wherein said means for effecting release of a projectile are associated with said valve means, said valve means being actuable to a position effecting release of a projectile.
Claim 6
Dependent Claim
19 words
Game apparatus in accordance with claim 4, wherein said fluid pressure means comprises a source of positive air pressure.
Claim 7
Dependent Claim
37 words
Game apparatus in accordance with claim 4, wherein said valve means includes means responsive to the presence of a projectile adjacent thereto to prevent actuation of said valve means to said position effecting release of a projectile.
Claim 8
Dependent Claim
63 words
Game apparatus in accordance with claim 2, wherein said means for effecting release of a projectile are associated with said valve means, said valve means being actuable to a position for placing said fluid conducting means in fluid communication with said conduit, and another position for effecting release of said projectile and placing said fluid supply means in fluid communication with said conduit.
Claim 9
Dependent Claim
37 words
Game apparatus in accordance with claim 7, wherein said valve means includes means responsive to the presence of a projectile adjacent thereto to prevent actuation of said valve means to said position effecting release of a projectile.
Claim 10
Dependent Claim
119 words
Game apparatus comprising a four-sided board including generally horizontally disposed transparent conduits, a first set of said conduits extending between respective opposite ends of said board, and a second set of said conduits extending between respective opposite side edges and intersecting said first set, a source of fluid pressure, fluid conducting means in fluid communication with said source and respective opposite ends of each of said conduits, selectively operable valve means operatively associated with said fluid conducting means and normally blocking fluid flow between said source and said conduits, projectile means in said conduits, the valve means associated with said first set of conduits including means for rEtaining said projectile means, and releasing said projectile means upon selective actuation.
Claim 11
Dependent Claim
119 words
Game apparatus comprising a four-sided board including generally horizontally disposed transparent conduits, a first set of said conduits extending between respective opposite ends of said board, and a second set of said conduits extending between respective opposite side edges and intersecting said first set, a source of fluid pressure, fluid conducting means in fluid communication with said source and respective opposite ends of each of said conduits, selectively operable valve means operatively associated with said fluid conducting means and normally blocking fluid flow between said source and said conduits, projectile means in said conduits, the valve means associated with said first set of conduits including means for rEtaining said projectile means, and releasing said projectile means upon selective actuation.
Claim 12
Dependent Claim
53 words
Game apparatus in accordance with claim 9, wherein the valve means associated with said first set of conduits are actuable to a first position for placing said source in fluid communication with said conduits, and a second position for releasing said projectile means and placing said source in fluid connection with said conduits.
Claim 13
Dependent Claim
16 words
Game apparatus in accordance with claim 10, wherein said source is a source of air pressure.
Claim 14
Dependent Claim
40 words
Game apparatus in accordance with claim 10, wherein the valve means associated with said first set of conduits include means responsive to the presence of projectile means adjacent thereto to prevent actuation of said valve means to the second position.
