Erno Rubik, the inventor of the famous Rubik's Cube game has released his newest puzzle game, the Rubik's 360. The new puzzle is spherical as opposed to cube-shaped and also transparent instead of solid. And if you thought the cube was hard to solve, the 360 is even harder. The puzzle has three spheres, with six coloured balls that have to each nest inside there corresponding slots. The puzzle was also designed so you literally can't put it down, otherwise your progress will be lost. The puzzle takes a lot more manual dexterity than the original and is less mathematically involved. it will be released this summer around the world.

The Rubik's 360 is set to repeat the success of the maddening Cube, which became an overnight sensation almost three decades ago and remains the world's fastest-selling toy.

Players must get the coloured balls from an inner sphere into matching slots on the outer sphere by shaking them through a middle sphere that has only two holes.

The 360 is spherical as opposed to cube-shaped, transparent rather than solid, but it's very, very Rubik's. It will take a clever mind to solve it, it has the original 6 Rubik's colours but it's more than a logic challenge, you've got to develop some skill as well.

When you actually put your hands around the Rubik's 360 for the first time you can't let go. You instinctively understand what the game is about and immediately want to start solving it, but first you have to find out how it actually works and how you can defy gravity.
