ABSTRACT:
The present invention involves a toy construction block set which includes at least two toy construction blocks and at least one toy construction block extender which are removable and attachable. A top of the block has a plurality of symmetrically arranged elongated protrusions for interlocking with a recessed bottom having a plurality of projections, on other, similar blocks. A toothed hole is located on at least one of the top, sidewalls, or a friction post of the block for angularly interconnecting with an elongated toothed interconnecting positioning rod located on at least one of the top, sidewalls, or bottom of a similar toy block. The elongated toothed interconnecting positioning rod when inserted into the toothed hole of a similar block or block extender permits a number of angular alignments between the blocks and the extender proportional to the number of teeth on the elongated toothed interconnecting positioning rod and toothed hole.
