The man got into a prison cell. The one who put him there decided to arrange a trial for him and put the key right in the chamber. In addition to keys, some doors can be opened using hint codes that can be read on the walls. Before the final door, you need to take special glasses with which you can read five tips and fold the final code. Please, note that the last code is generated automatically. And if you have hints like "0 is before 0" then you will have to start the game again. There is an error in the game and sometimes incorrect hints are generated.
