Solution: CAST spiral

This is the solution for the CAST Spiral puzzle.

This puzzle is in fact quite simple, the first step is to slide each pieces to have a stairs configuration such as the space between top & bottom stair is maximized.

CAST spiral solution 1

From there, a 2 pieces bloc should slide back (as pieces are very identical to each other, it is very difficult to post here clear pictures on which one should slide, by trials & errors, you should be able to find easily which bloc should slide) together with a torsion movement as soon as the two pieces on the top & bottom extremities will fit together again.

CAST spiral solution 2

From there, separating the 5 pieces is piece of cake.

To bring them back together, test pieces together two by two to find a configuration similar to the last one above. The spaces when pieces are slided must be maximized.

Once you have the blocks back like on the last pic above, bring the two parts together but not parallel; instead, rotate a little the small one for each parts being near to sliding in the other part free hole. When there, do a torsion movement to put them back together.

  3. Hi Justin,

    can you develop? Where is it not clear. That’s not an easy one to describe with pictures as all pieces are alike. If you describe where you lost the track, I can try to improve it.
