Magic Ball Cube
This is an awesome sensory puzzle that is achievable to solve from 4 and up typically. Move the inner balls (in a slide fashion) across to the empty space to manipulate the colours so that they eventually all match up.
You can only move the balls closest to the 'hole' so it takes thinking to work out where to move each ball so that you can match the colour ball to the same colour hole.
A great one for in the car that is NON tech in nature.
If dropped on a hard surface sometimes the plastic colour surrounds can come off and generally can be easily clipped back in (unless broken).
Not suitable fro children under y years of age.
