The invention relates to methods for creating three-dimensional puzzles that require disassembling an initial volumetric figure into individual components and then reassembling the individual components into the initial volumetric figure. The technical result is the creation of three-dimensional puzzles that have arbitrary volumetric figures as initial ones, the degree of complexity of assembly of which can vary widely from the simplest to the most complex. The component parts of the puzzles according to the claimed method are formed by cutting the initial puzzle figure with two groups of secant surfaces rotated in space relative to each other by 90 degrees, wherein the secant surfaces used to obtain the component parts are constructed based on guide lines with contours of a special shape. A description of the construction of contours of a special shape for forming secant surfaces is given in the claimed method.

A puzzle of chocolate-based material puzzle pieces is formed by providing a transfer sheet having a design of food-grade material on a first side of the transfer sheet and providing a puzzle piece template having passages shaped as pieces of the puzzle. The puzzle piece template is arranged on top of the first side of the transfer sheet. The passages of the puzzle piece template are filled with a chocolate-based material. After crystallization, the chocolate-based material in the passages of the puzzle piece template form the chocolate-based material puzzle pieces of the puzzle. The chocolate-based material puzzle pieces are removed from the template.
