Abstract: 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.
