The "next big thing" in the world of Rubik's Cube - the rotund Rubik's 360 - has been confirmed for launch on 15 July when the first UK-bound 360s will go on sale at Hamleys.

As we've brought you news of before, 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.

UK pricing has not been confirmed, but it's thought to be around £15.
