The present invention relates to a surface structure for joining blocks of a block toy having a magnet embedded therein, in which protrusion- and groove-shaped structures are formed on the surface of the block of the block toy having the magnet embedded therein, and the protrusion- and groove-shaped structures of each block are naturally engaged with each other such that the respective blocks can be securely joined to each other when the blocks are vertically joined, horizontally joined, and perpendicularly joined. |
