The invention relates to a logical mosaic-puzzle containing fifteen elements, out of which thirteen mosaic-puzzle elements (3, 4, 5) are arranged in three circles (I, II, III) extending partly into each other in a frame consisting of two parts (1, 2) in the assembled state of the toy. The puzzle-elements (3, 4, 5) belonging to the circles (I, II, III) fitted to each other accurately, however loosely, can be turned simultaneously along the axis of a circle each in respect to the other circles, further, one circle each consists of six-puzzle-elements (3, 4, 5), out of which -in the starting position- one element (3) forms the part of all the three circles (I, II, III), said puzzle-elements (3, 4, 5) are provided with projections (3', 4', 5'), three different shaped puzzle-elements have different projections which are connected to the groove between the casing (1) and the claming frame (2), resp. to the grooves (4'', 5'') on the puzzle-elements (4, 5) having been formed on the arches without projection. |
