A toy sphere consisting of a plurality of wheels that are rotatable around the radiuses of the sphere, each radius is in an even array of 45 degrees around the polar co-ordinates of the X, Y, and Z axes to form an array of eight wheels in each axis, where the circumferences of the three axes cross on the sphere, six wheels are made common to three axes of the said sphere, thus providing a total of eighteen wheels which are sized to 45 degrees of the circumference around each axis with the outer shape of the wheels conforming to equal 0.78539 radians. Each wheel is pulled inwards by equal spring tension to the centre point of the sphere to ensure that the periphery of each wheel abuts the neighbouring wheels and provide sufficient tension that when one wheel is rotated all the wheels around the sphere drive their neighbouring wheels into rotation. Decals can be attached to the front surface of the wheels to illustrate different colours and symbols which can be rotated at random to provide puzzles to amuse children of all ages.
