The present invention involves a toy construction block which includes a main outer structure having a top, four sidewalls and an open bottom. The top has a plurality of symmetrically arranged elongated projections for interlocking with Other, similar blocks and the open bottom has an underside to the top which itself has an elongated friction post extending therefrom. The friction post is hollow and is centrally and symmetrically located on the underside. The critical features are that the top has thereon a top recess in alignment with the friction post, a bottom recess within the friction post of the block, and at least one of the four sidewalls has a side recess therein adapted to receive an interblock connector. In preferred embodiments, a plurality of the four sidewalls has a side recess therein, and the top recess and bottom recess are formed by a continuous and complete orifice or hole directly through the block vertically.
