Quarks!® is a spherical 3D puzzle based on the sliding shell mechanism. It is also a brainteaser that makes the players familiar with some concepts of modern physics. Inspired by the world of quarks (subatomic particles that are one of the fundamental building blocks of all matter in the universe), Quarks!®  is an amazing game that will challenge anyone at any age. Holding the ball with both hands, twist the hemispheres in any direction to scramble the color pattern. The objective of the puzzle is to bring all the six colored spiral shaped quarks back to their original order. As an alternative to giving up, Quarks!® can easily be taken apart and recombined; a puzzle in itself. Once assembled, the Quarks! globe is returned to the original “out of the box” configuration.
