Uwe Meffert started designing rotational puzzles in 1970 with the invention of the Pyraminx.
Can you catch the rainbow?
A new challenge worthy of the avid puzzler’s interest. Instead of solving a color for six sides, arrange the curved rainbow-colored pieces so that each of six sides contain all nine colors! The rows turn smoothly in your hands, and the pieces flow seamlessly from one to the next. Not as smooth or seamless is the path to a solution, though!
