Abstract: A game for two to eight players comprising a game base upon which at least thirty game pieces, with different distinguishing features and values, are placed, and a method for playing the same. The game pieces are stacked upon one another, from the game base, forming planar levels of a three-dimensional structure. The game's concession for a myriad of game base types enable the construction of many diverse structures. The game pieces are identical in size and, preferably, a spherical shape. The game pieces are partitioned, according to their distinguishing features, into a plurality of sets.

Abstract: Regular rhombic dodecahedrons having faces with two aspects of two different kinds, each belonging to a same family, one by a bare surface, the other one by a shaded surface, are piled on a base having nests allowing those polyhedrons to be placed on top to build a composed pyramid. The general configuration of the visible faces of one kind and of the other kind will respond to specific rules of the game.

Abstract: A strategy game (10) that incorporates a stationary platform (12) that includes a set of three peg cavities (26) into which are inserted a set of three pegs (40), and a set of seven disks (52) each having a different diameter. The game is initially started by stacking the set of seven disks (52) on one of the pegs (40) with the largest diameter disk on the bottom and the smallest diameter disk on the top. The object of the game (10) is to move the stack of disks (52) from the one peg to another peg in the least amount of strategy moves and/or time. All moves must be accomplished without placing a disk having a larger diameter over a disk of smaller diameter.

Abstract: A puzzle is disclosed which consists of a three-dimensional geometric structure made up of a plurality of smaller three-dimensional structures, or pieces, that feature a plurality of indicia overlapping their edges. When correctly assembled, completed indicia appear on all surfaces, both exposed and non-exposed, as the portion of the indicium on each piece's surface matches the complementary portion of that indicium at the adjoining piece surface at the intersecting edge of the adjacent pieces. Construction consists of selecting a desired puzzle shape, selecting a set of smaller sub-division pieces which when assembled form the desired final shape, identifying the edges of the pieces which are adjacent to one another in the completed puzzle, selecting a desired set of indicia and overlapping the indicia over the edges such that completed indicia are observed on all adjoining faces.

Abstract: A three-dimensional puzzle which consists of several mutually permanently connected puzzle bodies which result in a regular tetrahedron in the assembled condition. In this case, all puzzle bodies are parts of irregular pyramids whose apexes, in the assembled condition, all meet at one point in the interior of the tetrahedron and whose bases form the tetrahedron surfaces in the assembled condition. All puzzle elements are also combined to a chain, specifically such that all puzzle elements, with the exception of the first and the last element, are in each case connected with the adjacent puzzle elements while they can be folded along an edge of the pyramid base.

Abstract: A three-dimensional puzzle, which consists of several mutually connected puzzle elements which result in a regular tetrahedron in the assembled state. A number of identical tetrahedron-shaped puzzle elements and a number of mutually identical puzzle elements of different sizes are provided which all have the shape of a closed spatial frame. In this case, the development is such that the inner sides of the legs of the frame-shaped elements are identical to the outer sides of the frame legs of each of the next-smaller elements or to the surfaces of the smallest tetrahedron-shaped elements. All elements are in each case connected with one another along one of their edges, specifically such that they can be folded and can be pulled apart a distance at least on one end. In this case, the elements are arranged such that they form a number of chains which have different lengths, are each placed against one another with their largest element and consist of puzzle elements which all have different sizes.

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.

Abstract: A game apparatus includes three designated construction sites and a discard site for each of one or more players, and a set of a plurality of playing pieces for each player. Each piece of a set of pieces is of similar geometric shape in one plane but each is of different perimetral size in that plane so that, beginning with the piece of largest perimetral size, all of the pieces of a set may be stacked, one on top of the other, to form a shape of constantly diminishing cross section such as a pyramid. The similarly sized pieces of each set are interchangeable. The apparatus also includes means, such as a playing board with designated draw locations or a box, for holding all playing pieces so that they may be drawn individually to be placed into play.

Abstract: A manipulative toy comprising a number of spheres serially attached in a closed loop or open chain, each sphere being attached to the next at a fixed point on its surface by a connector which allows relative rotation of adjacent spheres about a common axis through their centres.

Abstract: A puzzle includes a set of graduated size markers, each one having a different whole number indicia thereon, the indicia including the numbers 2 through 6. A base has a set of five positions on the face thereof, and one of the positions is a starting position and has a starting indicia associated therewith. Another one of the positions is a finishing position and has a finishing indicia associated therewith. At least one other one of the positions is a limited position and has indicia associated therewith designating certain ones only but not all of the whole numbers 2 through 6. The markers are stacked in a vertical pile at the starting position, and they are then moved seriatum from the pile to other positions with smaller markers always being placed above larger markers according to the puzzle rules. Only those markers having corresponding number indicia as the number indicia of the limited position may be moved to the limited position.
