said first blocks are generally in 'IT', shapes, the tops thereof face outwardly and form rotatable plates, a rotation axle is provided on the bottom of each of said rotatable plates, the bottom surfaces of said rotatable plates are all arciform, said rotation axles are pivotal -ly inserted respectively into said six axle rods of said central axle block, each of said first blocks is rotatable about one of said axle rods, the top surfaces of said rotatable plates each forms a smaller movable surface whi -26- -ch is exactly positioned at the center of one of said six sides; the tops of said second blocks are each in an shape, the rear sides of said tops abut respectively the four edges of said rotatable plates of said first blocks, the top surfaces of said second blocks each forms a small - er movable surface and are located reipectively at said four edges of said smaller movab16 surfaces of all said rotatable plates, said second blocks are provided on the lower rear sides thereof each with a second engaging block, the back of said second engaging block protrudes rearwardly to extend to the lower portion of one side of one of said rotatable plates, the protruding portion has an arciform top ledge which is in conformity in shape with and abuts against the arciform bottom surface of said one rotatable plate; said third blocks each has a top and a lateral sur -face perpendicular to each other and forming each a smaller movable surface, the intersection of said two small -er movable surfaces is located exactly at a corner where two neighboring sides of said five-layer intellectual cube orthogonally interconnect to each other, the inner side of each said third block abuts the outer side of said smaller movable surface of one of said second blocks, so that said top and lateral smaller movable surfaces of each said third block abut respectively said smaller mo-27- vable surfaces of two of said second blocks which are pro _vided on said two neighboring sides respectively, each said third block is provided in the rear a third engaging block, the top of said third engaging block is inserted to abut the bottoms of the protruding portions on the tops of said two second blocks, and is limited by said protruding portions of said second bloCks against drop- ping; said fourth blocks are provided on the tops there -of each with a smaller movable surface, all said smaller movable surfaces are positioned at the four corners respectively of all said first blocks, that is, the two inner edges of each of said smaller movable surfaces neighbor with the edges of two smaller movable surfaces of two of said second blocks on the same side of said intellectual cube and are perpendicular to each other, said four th blocks and said second blocks surround said six first blocks, the inner sides of said fourth blocks are provided each with a fourth engaging block and protrudes toward said rotation axle of one of said first blocks and toward said second engaging blocks of two of said second blocks which are perpendicular to each other, the top sur -face of the protruding portion of each said fourth block abuts on the bottom surfaces respectively of said smaller movable surfaces of said one of said first blocks and its corresponding second block, so that each said fourth blo -28- ck is limited not to drop; said fifth blocks are provided at the two lateral sides of said third blocks, the top on one side and the lateral surface thereof on another side of said five-lay -er intellectual cube are perpendicular to each other to form each a smaller movable surface, the intersection of said two smaller movable surfaces is also located exactly at a corner where said two sides 6f said five-layer intel - lectual cube orthogonally interconnect to each other, the inner side of each of said fifth blocks abuts an outer side of said smaller movable surface of one of said fourth blocks, the two outer sides of said fifth blocks are perpendicular to each other too, said fifth blocks are provided each with a fifth engaging block on the low -er inner portion thereof, the shape of said fifth engaging block is conformed partially with that of said third engaging block of one of said third blocks and partially with that of said fourth engaging block of one of said fourth blocks neighboring therewith, and abuts against and limited by said third block and said fourth block; said sixth blocks are provided on the eight corners of said five-layer intellectual cube, and each includes three outer surfaces as three smaller movable sur -faces perpendicular to one another, said three smaller movable surfaces are connected with one another with their outer edges, and abut said smaller movable surfa-29- is i ces of said fifth blocks with their inner edges, each said sixth block is provided with a lower sixth engaging block which is provided with a neck and an engaging portion, said engaging portion is in the shape in conformity with that of one of two laterals of each of three of said fifth engaging blocks of three of said fifth block neighboring therewith, and is restrained by-a plurality of recesses provided on said fifth blocks, so that said sixth blocks are prevented from dropping; by mutual restraint and limitation of all said neighboring blocks and the movability of all said smaller movable surfaces for changing positions thereof, all said smaller movable surfaces can be applied with colors or patterns, an intellectual enhancing effet can be gotten.
