Move the light colored pieces into the numbered spots.
Tresor translates to “safe” which is a fitting name for this puzzle! You need to maneuver the pieces into the correct combination as shown in the illustrated instructions in order to solve it. The inner wheel spins in a limited capacity allowing different pieces to move into different slots. Made in laser-cut wood, acrylic, and stainless steel by Siebenstein-Spiele.
