Tresor (translated as "safe"), another superb puzzle by Siebenstein-Spiele that will put your safe-cracking skills to the test. With its captivating design and a challenging solution, Tresor has everything to keep you entertained for a while.

Made with a combination of acrylic and laser-cut wood, plus the metal pins that you'll be moving from place to place, this is a sturdy puzzle that won't break that easily. There are seven of these pins, four of them marked with dots to represent numbers. The goal is to move the numbered pins from the starting position to the numbered positions marked on the frame. This is a type of puzzle that requires heavy planning to be solved, since the inner wheel doesn't move as freely as you'd think.

Once you get one or more pins inside the wheel to be transferred to another position, you'll be creating different blocking movements that you need to anticipate. This would already be a difficult puzzle without the movement constraint, but as it is, it gets very challenging, and frustrating at times. Even though the movement of wheel itself is smooth, it is somewhat a bit too tight when it reaches the edges. I tried to loosen it up a bit with a screwdriver, but was unsuccessful, since the screw is too tight and I was afraid I could break the puzzle. Nevertheless, the puzzle is perfectly doable as it is, and the tightness may vary from puzzle to puzzle.

Solving this is no easy feat, and the difficult of 8/10 may be a bit higher in my opinion. It took me days to solve this. There might a more efficient strategy to solve it, but I couldn't come up with one. Still, it's a nice challenge that will certainly not disappoint those who are looking for a good test to their skills.
