Frequently asked questions

The challenges interweave different knowledge fields and the solution process requires diverse skills.
The difficulty is subjective, yet empirically we can say:
For children: "My first set" - intended for children in Kindergarten- Second Graders. We recommend it as a joint activity for parents and children, for support, inclusion, and guidance, if needed and for encouragement and elation if not. Knowledge of the Hebrew alphabet is required.
Medium level of difficulty – the orange and white challenges (offline challenge) are also suitable as a family activity with ages 12+ and the blue set is recommended as the first challenge for adults
Hard difficulty level – the black, light blue (offline challenge) and red challenges are more or less at the same difficulty level
Very hard difficulty level – the green, yellow, and purple challenges. Not recommended for those who have not yet experienced

We recommend using a computer/laptop rather than a smartphone, as the user experience is significantly better, In the orange, black, and red sets, the importance of using a computer (and not a smartphone) becomes critical.
The white (medium) and light blue (hard) challenges are sets that do not require internet access during the solution, their hints also contain PDF files that can be downloaded, printed, and used as needed even in places without network access.

A QR code is displayed, on some sets, at the bottom of each box.
On other sets the QR code is on the cardboard ribbon wraped around the oter box
Scanning this code takes you to an array of web hints pages.
The hints are presented symbolically without the use of language and can accompany the solver step by step in the solution process until finding the lock code.
For the white set and the light blue set, you can also find PDF files that can and should be printed in advance.

  • Make sure to fasten the lock on the rubber exactly the way it was threaded (not the same in all boxes)
  • Be careful not to mix locks between the different boxes.
  • It is extremely important not to forget after reconnecting the lock to the box - to turn the dials of the lock numbers - that is, to change the position of the numbers so that the lock is locked.
  • Be careful not to turn the number dials while the lock tab is pressed to the open position.
  • For your attention, opening the locks for the first time removes our responsibility for the correctness of the lock code.
