My order arrived promptly and in excellent condition. IKOS are colorful and appear durable. We purchased 3 sets of IKOS--1 for each of our 3 grandsons to play individually or 2 or 3 together. We look forward to seeing the imaginative contraptions they build! I am sewing play mat - storage bags for each set and will ship them late this spring for Easter basket toys.More > < Less

Why are these blocks not block-shaped?

About IKOS

Geometry in Play

IKOS takes kids’ building toys to a whole new creative level. Unlike old building blocks, IKOS is made of interlocking shapes that come together to form a sphere. Kids aren’t limited by straight lines; the fun comes from making endless shapes, starting with a sphere and anything else they can dream up. Then they can take the pieces apart and figure out new ways to reconfigure them.

Whether they’re creating 3-D works of art or inventing games—IKOS bowling, anyone?—IKOS encourages kids to invent, innovate, and create.

The 26-piece set is made in the U.S. of the same eco-friendly, #2 recyclable material as milk bottles. IKOS is named for its geometry: an icosahedron (a solid, 3-dimensional object with 20 equilateral triangles for sides) transformed into a sphere. Playing with IKOS helps kids learn problem-solving, spatial relations, and STEAM—science, technology, engineering, arts, and mathematics—skills.

This spherical building system is even more interesting given its creation. Mike Wong went back to his high school to mentor students about starting a company and turning ideas into reality. Their idea was a great one—a combination 3-D puzzle and kids' building toy that offers kids unlimited ways to be creative.
