Visual Description

I was a bit confused as well when I first saw the Sweta Cross. It looked almost the same as Aluminum Cross, or First Cross by Wil Strijbos. What’s the point of buying one more puzzle that is basically the same?

Sweta Cross was designed specifically to be launched in Switzerland. If you place it in a wooden stand with a cross shaped embedding and look at it from the top — the whole construction will resemble a Swiss flag.

The reason for a different design and, consequently, the different mechanism inside is that Wil wanted to create something a bit easier than Aluminum Cross to appeal to a larger audience. Safe to say — Aluminum Cross is one of the hardest puzzles in the world that can put even the most seasoned puzzle fans to shame.

So, with the idea of making Aluminum Cross easier, Wil stayed at his friend Svetlana’s (or Sveta) home in Moscow and basically finished the whole design of the cross there.

So here you go, “Sweta” is an amalgamation of Switzerland and Sveta and it is quite different from the original aluminum cross.

This puzzle has four transparent “windows” which allow you to see very small ball bearings that are a part of its inner mechanism. 

The quality is amazing and on par with other puzzle from Wil.

Nevertheless, I would not say that this puzzle is “much easier” — it is still a very difficult challenge, so I would not take it lightly.

Main Features

The mechanism inside has the same idea as the aluminum cross, but takes a different approach to that. It always fascinated me how a puzzle engineer can fit two completely different approaches and mechanisms in the same shape and form.

In my own opinion — Wil combined the ideas of Aluminum Cross and First Cylinder in Sweta Cross. The mechanism inside incorporates both metal pins that hold the construction together and metal ball bearings that are essential when solving First Cylinder.


It’s an interesting puzzle, although a bit pricey. In any case, it is not as easy as it can be advertised — it is still a great challenge and might be super hard for inexperienced puzzle solvers.

A great gift, especially if you have friends from Switzerland and would like to give something truly cool and personal to them.

Where to buy

Assembly Tips

  • Listen closely to what happens inside.
  • There are several balls bearing that need to be moved into a certain position in order to make the pins that lock the cross move back. Just listen closely and try to move the ball bearing one by one and retract the 2 pins back inside the puzzle to unlock it.
