Together, the clever young detectives chase the mysterious Mister X through London. At Scotland Yard Junior, the players are hot on his heels: Mister X visibly escapes by taxi, bus, or underground. But where will he flee to next? Across the Thames? Back to Buckingham Palace? Beware: Mister X loves to outsmart everyone. However, he must give up if a detective moves to the same spot in London as Mister X at the same time; then he is caught! This works best when all players cooperate. Mister X wins if he manages to outsmart the detectives nine times. The detectives win together if they can catch Mister X three times. "Scotland Yard Junior" is a modified and simplified version of the classic game Scotland Yard for children aged 6 and up.
