Description
Friday afternoon and closing of school. But not for Luca, Ben and Mina. You have to sit down, strangely in room U1 in the basement of the Leonardo da Vinci secondary school. No trace of teachers, only a note asking them to solve the task at the board. Mina has no bock on this dusty hole with the flickering light on the ceiling. She wants to leave - but the door is closed! Now begins a mystery trip of the extra class for the three friends. Who is behind the whole thing? Finding out this is the job of the reader. He must solve the puzzles to find out on which side the story goes on. Hints can be hidden anywhere, creative solutions are needed, cut out, draw, bend - everything is allowed. And the time is running ...
