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 set with a plurality of puzzle pieces is provided. Each puzzle piece has at least four puzzle piece sections. The puzzle piece sections comprise a shape that is square, hexagonal, octagonal, circular or any geometric shape. Also, the plurality of the puzzle pieces comprises different geometric shapes such as I-shaped, T-shaped, L-shaped, O-shaped, S-shaped, J-shaped, and Z-shaped. The plurality of the puzzle pieces are arranged against, connected to each other, or stack on each other to shape the pattern of the puzzle pattern and complete the puzzle.

A three-dimensional logic puzzle is provided. The puzzle includes a plurality of identically shaped puzzle components of an irregular form. Each puzzle component is configured to engage with another identically shaped puzzle component via projections and recesses formed on the sides of the puzzle components. The plurality of puzzle components are interengagably assembled into the form of a predetermined three-dimensional geometric shape.

A twelve-piece tangram puzzle set is disclosed. The twelve-piece tangram puzzle set includes twelve pieces, the twelve pieces being formed in such a manner that an equilateral triangle is formed as a basic frame and is bisected into right-angled triangles by a first cutting line, second cutting lines, horizontal cutting lines and vertical cutting lines, and equiangular cutting lines so as to be divided into respective pieces 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, such that triangles (pieces 1, 3, 7, 9, 11) are symmetrical to triangles (pieces 2, 4, 8, 10, 12), and a trapezoidal quadrangle (piece 5) is symmetrical to a trapezoidal quadrangle (piece 6) based on the first cutting line.

A creative figure board game play and learning kit according to an exemplary embodiment of the present invention includes: a board game plate on which a plurality of unit figures having predetermined shapes is disposed at predetermined intervals to define a main set of figures; and shape piece blocks which are disposed on the board game plate by being rotated, moved, symmetric, and reversed along an outer circumferential portion of at least one of the unit figures, and connected to one another to define a sub-set of figures that divides a part of the main set of figures, in which the shape piece blocks have a single transformable shape piece block which is transformable to correspond to shapes of the remaining shape piece blocks.

The present invention relates to a puzzle comprising single and/or multiple puzzle pieces constructed from puzzle blocks, wherein a single puzzle piece is constructed from a single puzzle block and a multiple puzzle piece is constructed from at least two puzzle blocks, wherein each puzzle block describes a bipyramidal structure, wherein each side surface of the pyramidal structures is suitable for optimally supporting the puzzle block on one or more surfaces in a puzzle board. Also, the invention relates to a puzzle board suitable for solving both two-dimensional and three-dimensional puzzles, wherein the puzzle board is provided with a top surface and a bottom surface, wherein both the top surface and the bottom surface comprise a puzzle field consisting of regular positions forming a two-dimensional field, wherein each position is provided with an indentation in the puzzle board corresponding to the shape of a puzzle block belonging to a puzzle in accordance with the invention. In a third aspect, the invention relates to a kit comprising said puzzle and said puzzle board.
