Brainstring Advanced

Can you untangle this? The colorful strings of the Brainstring Advanced can be moved using the buttons on the outside. Move them from hole-to-hole to place one, two, or three buttons of the same color on each surface. But be careful: Make sure there is no knot inside!

New Brain Teaser: Brainstring Advanced

You can move the strings using the buttons on both ends but you can't move them in any arbitrary direction. There are given paths on the outside and some spots where the strings can pass each other.

Using the Brainstring Advanced

The goal is to get all the buttons in the right place without the strings being tangled and twisted around each other. So you have to find the right order of moves to untangle all of the strings. And keep in mind: You can't move them in every direction – just along the given grooves.
