Riddle: Mr. Green, Mr. Brown, and Mr. Black meet up for coffee one Monday morning. Mr. Green says, "Hey, do you realize that we're all wearing shirts of colors that don't match our names?". The man wearing the brown shirt says, "Wow, Mr. Green, you're right"! What colored shirt is each man wearing?
Answer: Mr. Green cannot be wearing the green shirt, because his statement that all three men are wearing shirts that don't match their names is correct. And he cannot be wearing the brown shirt, because the man wearing the brown shirt replied to his words, and let's be honest–it doesn't make sense to reply to your OWN words, right? This means Mr. Green can only be wearing the black shirt. Mr. Brown can either be wearing a green or a black shirt. The black shirt is already taken, so Mr. Brown is wearing the green shirt. And Mr. Black is wearing the brown shirt.

Riddle: There are two rooms in front of you. On the door to each room, there is a sign; only one of the signs tells the truth. The sign on the door to the first room says, "There is treasure here. A monster lurks in the other room,". And the sign on the door to the second room says, "The treasure and the monster are in different rooms,". Where is the treasure?
Answer: The treasure is in the second room. If the first sign is true, then the second sign is true, too. This contradicts the terms of the game. Therefore, the first sign is false, and the second sign is truthful.

Riddle: Claudia invented a game for her friends to play at her birthday party. Here is how it goes: she will place two marbles into a box– one yellow marble, and one purple marble. The player will have to pull out one of the marbles from the box. If the marble is yellow, the player will win $100.00, but if the marble is purple, the player will have to pay $10.00. Claudia decided to trick the players by putting two purple marbles into the box, rather than one yellow and one purple. Brian watched the other players lose the game one by one. But when it was his turn, he won $100.00! How did he do it?
Answer: Brian pulled out one of the marbles, and, without showing it to anyone, quickly put it in his mouth, being careful not to swallow it. Then, he pulled out the remaining marble, which was purple, and showed it to everybody. According to the rules, it meant that the marble Brian had chosen was yellow. Claudia had to admit it, otherwise, everyone at the party would know that she was a liar.

Answer: The three words are BACON, CUPCAKE, and LOVE. This riddle is open to many interpretations, so there are multiple answers. For example, BACON doesn't end with an E (unlike CUPCAKE and LOVE). However, CUPCAKE has three vowels (while BACON and LOVE have two each). On the other hand, LOVE is an emotion (while BACON and CUPCAKE are foods). No matter which word you pick, there is at least one reason for it being correct.
