The invention relates to a logical toy. The flat play-field (5) of the logical toy is formed by toy elements (3) movable in a house (1), and associated with information-carrier (9), mainly marked with colour. The essential feature of the invention is that the house (1) has at least four circular nests (2). The toy elements (3) are almond-shaped plates in top view, the envelope curve of which at least on two sides is a circular arc of about the same radius as the radius (R) of the nest (2) and are slidable along the circumference of the nest (2) forming circular toy unit (4) of the same number as the number of nests (2). These toy units (4) are arranged in the play-field (5) so that two adjacent toy units (4) overlap each other by the area of a single toy element (2). Each toy unit (4) is turnably embedded in house (1) and provided with a driving element (6) capable to turn all of its toy elements (3) jointly in the nest (2). This invention may offer exciting entertainment for children and adults alike. The solution of the toy can be made more difficult by increasing the number of the toy units.
