The block set features that a plurality of block units of the same color are integrated so as to build a block bar, and two or more block bars respectively of different colors are crosswisely combined to build a block bar combination, and two or more block bar combinations interconnect one another to thereby build a variety of structures having two or more colors, wherein the block bars of the same color are symmetrically disposed.
