Hi Alice, you have to turn the middle part, align the oranges and then you get the answer 2

Asumiendo que los círculos de en medio se pueden mover independientemente cada uno y que los números representan el orden sería:

Primera combinación.... alinear el segundo circulo de manera que las líneas naranjas toquen las runas y, mover el círculo central de manera que las líneas naranjas conecten 

Segunda combinación.... Alinear de la misma manera con las líneas naranjas de manera que conecten 

Tercera combinación... En este caso alinear con las líneas amarillas 

Cuarta combinación... De igual manera con las líneas amarillas 

Se usa las líneas naranjas por el hecho de existir un espacio de dos runas para la combinación y la amarilla porque no hay espacio 

I saw this a few hours ago and was surprised at the slowness to respond, except its not quite so simple as other puzzles have been perhaps. I hadn't got round to studying sufficiently  yet, 

I would say if the answer is as simple as Pilechiefs  its 4.

I  agree with Pilechief, ie I think the answer is No 2. When rotating the middle section only the orange lines can join up, and they then link the two runes shown in No 2.

and I will go with half the meaning of life: ie  2 1

ie rotate inner disk to align orange lines and then rotate whole disk ??

(I like Franz's logic but the yellow lines don't join together and presumably they should)

well here goes.

First rotate the outer wheel counter clockwise to align the orange lines this will then join them to the two runes in box 1. Then press the button in the middle to lock the two wheels together and rotate them both clockwise to put the picture in the center in a vertical portrate position that will then aline the orange lines with the runes  in box  2. and open the box. 

So I think the answer is 12.

But then what do I know, could never do a rubix cube either.

The answer is 2

Too easy... Nbr 2.

Step up The difficulty please ;-)
