A tiling puzzle includes a low-profile packing frame having a raised continuous border and a flat recessed surface area within the border. A plurality of multi-sided puzzle pieces are adapted for being assembled together on the recessed surface area of the packing frame. A frame indicium is located on the packing frame. A multi-sided solution key is adapted for residing within the recessed surface area of the packing frame directly adjacent the frame indicium. After properly placing the solution key within the packing frame, the puzzle is solved by assembling the puzzle pieces together on the recessed surface area in a single functional arrangement such that the solution key and all puzzle pieces occupy the entire recessed surface area within the packing frame without gaps or overlaps.

A three-dimensional puzzle comprising a plurality of cuboid puzzle blocks together forming a predetermined three-dimensional puzzle shape, wherein each puzzle block comprises either a male or a female connecting element on each of at least three sides of the puzzle block; wherein the connecting elements for the respective puzzle block are configured such that each puzzle block is unique.

New and unique puzzle mechanics, systems, and methods are described herein. A puzzle grid comprising linearly arranged intersecting words, with each individual letter placed on a separate puzzle tile, may be divided into a plurality of puzzle pieces, where each puzzle piece is formed of one or more contiguous puzzle tiles. Each puzzle piece shape conforms to one of a predefined set of shapes. To mix up the puzzle grid, identically shaped puzzle pieces may be randomly shuffled and rotated if required so that the puzzle layout remains unchanged whereas the letters are scrambled. Also puzzle pieces whose shape exhibit rotational symmetry may be optionally rotated within the puzzle layout. Letters may maintain upright legibility. A user may then attempt to solve the puzzle by swapping identically shaped puzzle pieces and optionally rotating puzzle pieces whose shape exhibit rotational symmetry.

A puzzle kit and a puzzle constructed from said puzzle kit. The puzzle kit comprises a three dimensional substrate having an outer surface, and a plurality of puzzle pieces that cannot interlock. Each puzzle piece has a first surface and an opposite second surface and a thickness defined between the first and second surfaces. Each puzzle piece comprises first attachment means and the outer surface of the substrate defines a plurality of complementary second attachment means, such that the first attachment means and the second attachment means magnetically attach each puzzle piece to the outer surface. The first attachment means comprises a projection extending from the second surface of the puzzle piece. The second attachment means comprises a hole to partly receive the projection.

A self-adhesive stacked set including a plurality of stacked bodies is provided. The plurality of stacked bodies form a three-dimensional geometry, and a top view shape of the plurality of stacked bodies includes a triangle and a quadrangle. Each of the stacked bodies includes a plurality of stacked layers, and the plurality of stacked layers are stacked on each other. A rear surface of each of the stacked layers has an adhesive region, and the plurality of stacked layers are stuck to each other via the adhesive region.

This application discloses a new toy track system based on hexagonal tiles. This unique system allows for pleasing and complex track layouts in a small area. The layout activity itself can be viewed as a puzzle or game. The track tiles may be joined to one another by puzzle tabs or by magnets along their edges. The track, whether slot or other construction, follows arcs on the hexagons joining midpoints of the hexagon edges. The tile designs are chosen from the unique set of tile designs having such arcs that cross at most once on a single tile.
