MoYu Rainbow Ball

MoYu Rainbow Ball

MoYu Rainbow Ball is a ball-shaped puzzle from MoYu. Unlike a 3x3 cube, it has no layers to turn. Your task is to move seven coloured balls so that each one ends up in the hole marked with a ring of the same colour. The rule is simple, but solving it takes some planning, because you move the balls using the free space inside the sphere.

How to solve the Rainbow Ball

After scrambling, the balls sit in random spots, and the rings around the holes show where each of them belongs. You don't take the balls out or rearrange them by hand. You slide them around inside the puzzle. That means you have to think a few moves ahead: putting one ball in place often means temporarily moving another one out of a spot you have already solved. There are no algorithms to memorize, because you find the solution through trial and error and logical thinking. Some users say that pushing the balls takes a bit more force than you might expect, so don't count on movement as smooth as on a speedcubing puzzle.

Who is it for?

The Rainbow Ball works well for younger kids who can't solve a 3x3 cube yet but enjoy logic toys. All you need to do is match the colours, so it's easy to understand. It's also a good fit for older users who want a puzzle to fiddle with at the desk or while travelling. Cubers looking for a puzzle for timed practice probably won't be interested, as this is a casual brain teaser rather than a speedcubing puzzle.
