Reptangles are 'geometry turtles'- building blocks which lock together to create hundreds of geometric shapes. The set contains 24 turtles and more than 50 multi-level puzzles. However, the unique mathematical value of Reptangles comes with the geometrical shapes that can be made. The accompanying booklet guides you through creating various structures and symmetries with a seemingly endless supply of polyhedra to create. There are simple shapes to build, or if you are feeling more ambitious, this set will guide you in creating a lesser rhombicuboctahedron, a trucated cube or a reflecting tripod. Exceptionally high quality, incredibly colourful and thoroughly well thought out, Reptangles is an outstanding idea!
