RELATED APPLICATIONS 
     The present application claims priority to Belorussian patent application number u 20170176 filed on Apr. 29, 2017 and Patent Cooperation Treaty application number PCT/J B2018/000406 filed on Apr. 18, 2018 and incorporated by reference herewith in its entirety. 
     RELATED ART 
     The present invention relates to a magnetic construction toy for engaging games and may be used to assemble three-dimensional figures. 
     BACKGROUND OF THE INVENTION 
     The state of art shows that there are construction toys containing magnetic elements inside modules. The closest equivalents are as follows. Wooden magnetic construction toy consisting of elements in the form of three-dimensional geometric figures with magnets located inside certain faces thereof. 
     Not all the faces of figures contain magnets which prevents using all the element surfaces to assemble different complex structures, while at connection of two elements of the same pole magnetic faces repel one another. Drawbacks of the product are: limited inventory of figures to be assembled, inconvenience in use, complicated use and low playing properties. The closest equivalent of the specified utility model is magnetic building blocks according to the U.S. Pat. No. 7,247,075 consisting of three-dimensional modules made in pyramid shape, each containing magnetic disks, one per each face and two in the bottom. As one magnet is fixed to one face, the same pole magnetic faces repel one another at connection of two elements. 
     When complicated shapes are assembled the form loses its stability due to a magnet located approximately in the middle of the face and no fixation of edges of the elements by means of magnetic field. Drawbacks of this magnetic building blocks are: the use of one figure type only, as well as number and location of magnets insufficient to provide secure fixation of elements to each other, which reduces the inventory of figures to be assembled with this magnetic construction toy, complicates its use and limits its playing properties. 
     The task of the proposed utility model is to improve playing properties of magnetic construction toy, expand the inventory of structures assembled with this magnetic construction toy, as well as simplify composition of such structures and ensure stability thereof.
