Steinar stabs the puzzle pieces
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Steinar grabs the easily accessible corner piece from between two blocks. He uses a knife to stab the centre piece and lift it out of the castle. He tries to retrieve the final edge piece by tapping it out of the tower and into a more accessible position using his knife. Unfortunately, he knocks a couple of blocks off the tower in the process, and ends up in joint third place, along with everyone else who failed.
