The challenge is to turn the cube into a robot and then work out how to make it into a cube again.  Not as simple as it looks!
This product has a number of benefits. It can be used as a fidget toy during periods of sensory overload or anxiety. The cubes can be moved around in different directions in a quiet and non disruptive way.
There are also cognitive benefits. How can you manipulate the cubes to make a square?  Fine motor skills are also exercised in learning how to manipulate the wooden fidget puzzle cubes into different positions.
