“With YOGA I, Pelikan has sensationally brought my latest masterpiece to life. You might think, “not another packing puzzle!” However, the name itself hints at the fun to be had. Not only will your brain be bent and stretched while solving it, but the pieces themselves will be too. They are so simple – 8 identical pieces, each consisting of 4 cubes. The clever part is that two of the 4 cubes in each piece are connected by an axis. This allows each piece to take on 4 possible shapes. If the box didn’t already contain fixed blocks, the challenge would be practically nonexistent. As it is, the task is to find the only possible combination of shapes and then fit it into the box. An absolutely tricky business. I’m proud that Pelikan didn’t hesitate long and that together we were able to give the puzzle such an appealing look.”

The goal of the puzzle is to fit all the pieces inside the box so that no pieces stick out of the box.
