You are in a study of Paul Slaumi, a French professor who devoted his life to puzzle solving. He was very good at that – he managed to crack each and every puzzle he ever dealt with. Only the last one became fateful for him … The door clicked shut behind you and can’t be opened; on a screen the time of 60 minutes appeared and is relentlessly counting down. In this room you will have to cooperate and think a lot; the professor might have been an eccentric, but a brilliant one. Will you be able to solve this superpuzzle? And one more question – do you like balls?
