ABSTRACT:
The present invention relates to a game, notably to a three dimensional noughts and crosses type of game.
BACKGROUND TO THE INVENTION
Noughts and crosses, or tic-tac-toe as it is also known, is a game in which two opponents each try to complete a line of three or more noughts or crosses on a grid layout, whilst at the same time preventing the opponent from completing a line, by each in turn entering a nought or cross respectively on the grid. There are a number of variations of this game, but each requires a line of a specified number of either noughts or crosses (or other pairs of symbols) to be completed. For simplicity, the invention will be described hereinafter in terms of the completion of lines of noughts or crosses.
In order to make the game more challenging, it has been proposed to play the game in three dimensions on three or more layers, each having receptacles laid out in a grid pattern and adapted to receive a coloured marble or other game piece. However, such truly three dimensional games are cumbersome and often complex to play.
I have now devised a simplified form of such a three dimensional game which is compact and simple to play and yet provides a wide number of permutations of play.
SUMMARY OF THE INVENTION
Accordingly, the present invention provides a game comprising the combination of:
a. a polygonal three dimensional body member having at least four exposed contiguous planar surfaces which surfaces intersect along lines of intersection which lines terminate at each end thereof in an apex where three or more of said surfaces intersect;
b. a plurality of games piece anchorage points provided on or in association with at least three of said surfaces, each anchorage point being adapted to receive and locate a games piece upon said body member in specified geometric relationship to other games pieces, an anchorage point being located at each of at least three of said apices, at least one anchorage point being located upon each of at least three of said lines of intersection, and at least one anchorage point being located upon each of at least three of said surfaces; and
c. at least two series of games pieces adapted to be received by said anchorage points.
Preferably, the anchorage points are located symmetrically upon the body member and all exposed surfaces of the body member are provided with at least one anchorage point.
The body member may be of any suitable shape and size. The exposed faces may thus be of triangular, square, trapezium, hexagon, octagon or other shape. However, it is preferred that the surfaces be of equilateral shape, notably square, hexagon or octagon shape so that the body presents a series of uniform surfaces and has symmetry in all three axes so that the game can be played with the body in any orientation. Preferably, the body is a right pyramid, a cube or a right octahedron or dodecahedron.
For convenience, the invention will be described hereinafter in terms of a cube body member.
Such a body member has six exposed faces and, preferably, all six faces are available for use in playing the game. However, if desired, one face may be excluded as being the base face upon which the cube rests and, as such, is not an exposed face for the purposes of playing the game as described below. Each face presents a right square surface which intersects with two adjacent faces to form a corner of the cube. That corner is an apex of the body member and there are eight such apices to the cube. Two adjacent surfaces intersect along the lines linking each at the apices to an adjacent apex to form the side walls of the cube and each cube has six side walls, including the top and bottom walls of the cube. Each wall can be of any suitable size and colour, but will typically be from 2.5 to 10 cms square. If desired, the wall may be dished inwardly or outwardly to provided an aesthetic shape to the body member, in which case the lines of intersection of the exposed surfaces will be curved rather than straight. For convenience, the invention will be described hereinafter in terms of a cube having substantially flat wall surfaces.
The surfaces can be the exposed surfaces of a solid body, for example a die cast, extruded or other moulded plastic cube or a machined wooden or metal cube. However, the cube may be a hollow member made by linking together six flat square panels of a suitable material to form the side walls of the cube. If desired, such a hollow cube can be made by snap fitting the wall panels to one another using suitable securing means along each edge of the panel, or by means of a stem or cup extending normal to the plane of the panel and engaging with a central support spider member located within the resultant cube. In a particularly preferred embodiment, the cube is formed in two halves as hollow mouldings which are a snap fit engagement on one another to form the complete cube. For convenience, the invention will be described hereinafter in terms of a solid cube.
The cube is provided with anchorage points by which games pieces can be secured to the body member. These anchorage points can take a wide range of forms, depending upon the nature of the games piece used. Thus, the anchorage point may take the form of a metal disc or the like where the games piece is provided with a magnetic foot or vice versa; or where, the cube is made from a ferro-magnetic material, the anchorage point can take the form of a break in the paint or other surface finish to the cube which identifies the position at which such a magnetic games piece is to be affixed to the cube. The anchorage point may take other forms, for example a disc of the hooked portion of a hook and eye type fastening, the games piece carrying the corresponding eye portion; or vice versa. However, it is preferred to provide the anchorage by means of the push fit engagement of a stem carried by the games piece in a socket or recess in the body member or vice versa. The game piece may be locked in position by means of a bayonet type mounting, but a friction push fit is usually satisfactory.
For convenience, the invention will be described hereinafter in terms of a games piece having a shank piece which is a friction push fit into a socket in the body member. Such inter-engaging shanks and sockets can be of any suitable size and depth. If desired, where the cube is made from a series of panel members, the shank can carry a radially extending pin or lug and the socket can have a corresponding radial slot so that the shank and its pin can pass through the aperture in the panel provided by the recess. The games piece can then be locked in position by twisting the games piece about the longitudinal axis of the shank to carry the radial pin out of register with the radial slot. Alternatively, the sockets can carry circumferential ribs which engage radial ribs on the shank of the games piece to provide a snap fit or screw fit locking of the shank in the socket. The shank and the socket are preferably of a generally circular cross section. However, they may have other forms, for example a squared or triangular cross section, so that the games piece adopts a fixed orientation with respect to the body member once the stem has been engaged in the socket.
For convenience, the invention will be described hereinafter in terms of a body member carrying a plurality of circular sockets into which the cylindrical shanks of pins carried by the games pieces engage as a friction push fit.
The game of the invention is characterised by the layout of the anchorage points upon the body member. It has been proposed in U.S. Pat. No. 4,129,303 to form a solid cube and to provide games piece anchorage points upon the surfaces of the cube. The anchorage points, are laid out in a conventional grid pattern on each exposed face of the cube with playing lines joining the anchorage points extending from one face onto an adjacent face. However, none of the anchorage points are located at the apices of the cube or on the lines at which one wall of the cube intersects another. In the present invention, by locating the anchorage po
