Abstract
Abstract A game apparatus includes a horizontal playing surface divided into individual playing areas by vertical intersecting walls. Play involves the assembly of geometrical building blocks within each playing area to progressively construct an identical segment of a building structure that is symmetrical across the walls and that includes the walls themselves. The building blocks must be arranged in predetermined layers of diminishing width and length to form a pyramidal structure. The upper wall surfaces are configured as stairways, causing the completed building structure to have the appearance of a Mayan temple. The method of play involves use of chance instructions to regulate assembly of the layers of building blocks. The players alternately add or remove building blocks as instructed until one player has completed a segment of the building structure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A three-dimensional construction game apparatus, comprising: a base having a horizontal playing surface; a pair of centrally intersecting walls positioned across the playing surface, said walls having side surfaces extending from the playing surface to separate individual playing areas thereon, the upper surfaces of each wall being inclined inwardly and upwardly from its outer ends toward its transverse center; a plurality of building blocks adapted to be stacked within the individual playing areas in solid horizontal layers that abut said side surfaces and which are symmetrical across said walls, the completed stacks of building blocks within the individual playing areas each constituting an identical segment of a pyramidal building structure that includes said walls; and means for directing sequential placement of building blocks within the individual playing areas as the game progresses.
Claim 2
Dependent Claim
132 words
A three-dimensional construction game apparatus, comprising: a base having a horizontal playing surface; a pair of centrally intersecting walls positioned across the playing surface, said walls having side surfaces extending from the playing surface to separate individual playing areas thereon, the upper surfaces of each wall being inclined inwardly and upwardly from its outer ends toward its transverse center; a plurality of building blocks adapted to be stacked within the individual playing areas in solid horizontal layers that abut said side surfaces and which are symmetrical across said walls, the completed stacks of building blocks within the individual playing areas each constituting an identical segment of a pyramidal building structure that includes said walls; and means for directing sequential placement of building blocks within the individual playing areas as the game progresses.
Claim 3
Dependent Claim
47 words
The game apparatus of claim 1 wherein said building blocks comprise: a set of rectangular blocks having a square plan configuration; a set of bevel blocks having an upwardly inclined surface at one side; and a set of cornerstones having upwardly inclined surfaces at two intersecting sides.
Claim 4
Dependent Claim
73 words
The game apparatus of claim 1 wherein said building blocks comprise: a set of rectangular blocks having a square plan configuration; a set of bevel blocks having an upwardly inclined surface at one side; and a set of cornerstones having upwardly inclined surfaces at two intersecting sides; the building blocks being adapted to be stacked in horizontal layers having progressively decreasing length and width from the bottom of each stack to its top.
Claim 5
Dependent Claim
116 words
The game apparatus of claim 1 wherein said building blocks comprise: a set of rectangular blocks having a square plan configuration; a set of bevel blocks having an upwardly inclined surface at one side; and a set of cornerstones having upwardly inclined surfaces at two intersecting sides; the building blocks being adapted to be stacked in horizontal layers having progressively decreasing length and width from the bottom of each stack to its top; each stack comprising a plurality of paired layers in which the lower layer is comprised only of one or more rectangular blocks and the upper layer is comprised of a cornerstone either abutting said upright side surfaces abutting bevel blocks surrounding rectangular blocks.
Claim 6
Dependent Claim
63 words
The game apparatus of claim 1 wherein the inclined upper surfaces of said walls are configured as stairways leading upwardly from the edges of the playing surface to its center, the height of the stairways being slightly greater than the height of the stacked layers adjacent to them and the pitch of the stairs being equal to the pitch of the stacked layers.
Claim 7
Dependent Claim
55 words
The game apparatus of claim 1 wherein said playing surface comprises the upper surface of two identical rectangular baseboards placed in side-by-side abutting positions beneath said walls; said walls having outer ends that overlap and engage outer edge surfaces of said baseboards to maintain them in abutment with one another during play of the game.
Claim 8
Dependent Claim
42 words
The game apparatus of claim 1 wherein the walls comprise two planar wall members having complementary slots that open either upwardly or downwardly at their respective centers, whereby the wall members can be selectively interlocked with one another in perpendicularly intersecting positions.
Claim 9
Dependent Claim
74 words
The game apparatus of claim 1 wherein the walls comprise two planar wall members having complementary slots that open either upwardly or downwardly at their respective centers, whereby the wall members can be selectively interlocked with one another in perpendicularly intersecting positions; the wall member having a downwardly open slot also having a central cap at its center, with an open shelf extending through the cap adapted to support a deck of instruction cards.
Claim 10
Dependent Claim
72 words
The game apparatus of claim 1 wherein the walls include a central cap at their center; the inclined upper surfaces of said walls being configured as stairways leading upwardly from the edges of the playing surface to its center, the height of the stairways being slightly greater than the height of the stacked layers adjacent to them and the pitch of the stairs being equal to the pitch of the stacked layers.
