Scenario Riddles

Scenario Riddles, as the name implies, present a scene one must mentally view in order to solve the riddle. The best approach is to read very carefully and picture the scene in one’s mind. Taking the riddle step-by-step should provide you with the answer to these thought-provoking riddles.

The Rusty Kettle

On a dark, stormy night, a man who owned a casino invited some friends for a visit. The men all placed their money on the table right before the lights went out. When the lights came back on, the money was gone. The owner wanted to discover who stole the money. So, he put a rooster in an old rusty bucket. He told everyone to get in line and touch the bucket one at a time when he turned the lights off. He said that the rooster would crow when the robber touched it. After everyone touched it, the rooster hadn’t crowed. Then the man told everyone to hold out their hands. After examining all the hands, he pointed out who the robber was. How did he know who stole the money?

The Jumping Man

A dead body is found at the bottom of a multi-story building. Seeing the position of the body, it appears evident that the person jumped from one of the floors, committing suicide. A homicide detective is called to look after the case. He goes to the first floor and walks in the room facing the direction in which the body was found. He opens the window in that direction and flips a coin towards the ground. Then he goes to the second floor and repeats the process. He keeps on doing this until he reaches the last floor. Then, when he climbs down, he tells the team that it is a murder not suicide. How did he come to know that it was a murder?

An Heir for the King

A king has no sons, no daughters, and no queen. For this reason, he must decide who will take the throne after he dies. To do this he decides that he will give all of the children of the kingdom a single seed. Whichever child has the largest, most beautiful plant will earn the throne. At the end of the contest all of the children came to the palace with their enormous and beautiful plants in hand. After he looks at all of the children’s pots, he finally decides that the little girl with an empty pot will be the next queen. Why did he choose this little girl over all of the other children with their beautiful plants?

The Rescue of the Beautiful Rose

Once there was an evil wizard. He took three women from their homes and turned them into rose bushes that looked exactly alike and put them in his garden. One of the women had a husband and children and begged the wizard to let her see them. He agreed. At night he brought the woman to her house. In the morning he came and took her home. The husband decided to go rescue her. So, he snuck into the wizard’s garden early in the morning. He stared long and hard at the three identical rose bushes trying to figure out which could be his wife. Suddenly he knew the answer and he took his wife home. How did he know which rose bush was his wife?

Hidden in a Lake

Dr. Miller was staying with his cousin, Alfred, in Alfred’s lakeside cabin. They were setting up Alfred’s will. Since Dr. Miller was Alfred’s closest living relative, much of Alfred’s estate was being left to him. One day, Alfred went to Dr. Miller very upset. “Doctor,” he began, “I have just found out that an old enemy is out to get me. He is coming very soon. Where will I go? Where can I hide? If he finds me, he will surely kill me. I do not have time to leave this cabin and hide in the woods.”
Dr. Miller thought for a moment, and then grabbed a 5′ long bamboo fishing pole, with a diameter the size of a quarter. “Alfred, follow me out to the lake. This lake is 4′ deep. If you lie on the bottom of the lake and breathe through this pole, your enemy will never find you. I will be in the bulrushes with a shotgun, and I will shoot him when he comes. I will swim down to find you when he is gone.”
Alfred thought that was a great idea and went down in the lake with the bamboo pole in his mouth. A few hours later, a ranger passed by. He found Alfred’s body. Dr. Miller told the police of the circumstance, and that Alfred had probably panicked, and died. Police arrested Dr. Miller on the charge of murdering Alfred. Why?
