Mind Puzzle
Did you know that there is a World Puzzle Championship? It has been held every year since 1992 and people from all over the world participate. Before you can become the champion, you have to solve many riddles.
3 pictures: one minute to test your observation, analysis and reasoning skills!
1.One day at noon, Detective Tutu was invited to his friend’s house for lunch. As soon as he entered the house, he found his friend tied up on the bed (as shown below). His friend said, “A group of criminals came last night, tied me up, and took away your bank passbook that was stored with me.” Detective Tutu only looked around and knew that his friend was lying. May I ask: What details exposed his friend’s lie?
2.Two couples whose names are unknown came to the hotel. One of them is a real couple, while the other is a wanted criminal who killed her husband and her lover. Unfortunately, just like in the comics, because the wanted photo cannot be seen clearly for some reason, we don’t know which couple is the criminal! Fortunately, the hotel has received the wanted order, so they were alert and called our great detective Tutu. The great detective Tutu only noticed one thing and knew which couple was the criminal. Please ask: Which couple is the criminal?
3.One day, Detective Tutu received a report that the laboratory data was stolen by a spy! After retrieving the hidden camera, the camera clearly captured the scene when the spy came in. It was found that there were two spies A and B who sneaked into the laboratory to steal the data. It was obvious that the safe that the later spy saw was empty. Since the two came in through the same window, please ask: Who came in first, spy A or spy B?
