The Rubik's Cube has gotten yet another update with the announcement of the Rubik's 360, due to go on sale in UK shops this summer.

The new Rubik's brain-teaser claims to take the puzzle into a "new dimension" and gets a round, rather than square design.

10 centimetres or so in diameter, the 360 is described as a transparent plastic sphere housing two further internal transparent spheres, both independently suspended on a rotating axis, with six balls at its centre.

The object of the puzzle is to steer the coloured balls through holes in the spheres and into their respective coloured home slot domes on the outside.

Inventor Professor Erno Rubik says: "I feel that the Rubik's 360 is one of the most innovative and exciting puzzles we've developed since the Cube - adopting elements of my original design, challenging the solver to use skill, dexterity and logic. But it's a more kinetic challenge, more physical, because gravity is involved. We all have great hopes for it".

The new puzzle will cost around £15 when it launches later this year. - learn about it / talk about it / deal with it At parents can find all the advice they will need to keep their children safe online.
