BUILDING GENIUS
BUILDING GENIUS brings together three of MOLUK’s most celebrated toys — Hix, Mox, and Oibo — in a versatile 9-piece set. Each award-winning design opens a unique world of sensory discovery: cones that flip and fold into new shapes, elastic cubes that bounce and stack, and talkative balls with a big appetite for play.
Together, they offer a more organic approach to building and construction — one that feels alive in children’s hands. As they stack, balance, squeeze, and invent, children refine motor skills, experiment with geometry, and explore cause and effect in playful ways.
BUILDING GENIUS grows with the child, revealing new uses and challenges year after year. Soft, silent, and timeless in design, it is a construction set that inspires creative minds for a lifetime of play.

Award-Winning Trio
Bringing together Hix, Mox, and Oibo, BUILDING GENIUS unites three acclaimed toys in one set. Each piece has received international recognition for its design and developmental value.
Organic Approach to Building
Unlike rigid blocks, these shapes flip, fold, bounce, and balance in surprising ways. Children discover construction as a living, sensory experience rather than a static structure.
Grows with the Child
From first stacking attempts to complex patterns and pretend play, the set reveals new possibilities at every stage. It keeps pace with children’s curiosity year after year.
Development Through Discovery
While inventing games, children refine fine motor skills, practice hand-eye coordination, and gain a tangible sense of geometry. Learning happens naturally through joyful exploration.
Safe, Silent, Timeless
Soft silicone pieces are quiet, safe to handle, and durable enough for years of play. The design remains as fresh and relevant in the classroom as in the home.

Together, they embody MOLUK’s design philosophy — abstract yet friendly, multifunctional, and always evolving with the child.
