We produce square bricks that are the same size as the traditional mid size bricks and are 100% compatible with traditional squares, but we have added dozens more ways of joining the bricks, and added a triangle. This makes it possible to make far more shapes from the same number of pieces, (any setover 200 pieces comes with instructions for over 100 models). One can also make circles curves spirals and gears that were never possible with traditional sets. The sets are more challenging, more exciting and just more fun.
