The final player has no loyalty to either team, but is committed to the game and never leaves until the end. What game is it?

Riddle:
Where does tomorrow come before yesterday, and where does today come before yesterday?
Answer: The answer is in dictionary. Explanation: Well the logic used to solve this riddle is that in the dictionary, words or letters are organized Alphabetically and hence Today comes before Yesterday because in the alphabet order alphabetically, the letter T comes before the Letter Y. I hope this helps

Riddle:
Zane is a big boss in a hugely successful company. Every week, however, he finds out that one of his worst employees has been stealing his documents. After a whole year of stolen documents, Zane rounds up his three worst employees– Kelly, Raymond, and Natalia– and questions them. Kelly says, "Raymond has been stealing your documents!". Raymond says, "I haven't been stealing your documents!". Natalia says, "I haven't been stealing your documents, either!". Only one of the employees is telling the truth. Who has been stealing the documents, and which employee is telling the truth?
Answer: Natalia has been stealing the documents. Raymond is telling the truth. If Kelly was the one stealing the documents, then she would be lying, and Raymond would be telling the truth. But then, Natalia would also be telling the truth, which goes against the condition that only one employee is telling the truth. If Raymond was the one stealing the documents, then he would be lying, Kelly would be telling the truth, and Natalia would also be telling the truth. This also contradicts that only one employee is honest. If Natalia was the one stealing the documents, then she is lying. But then, who is telling the truth? It's not Kelly, because if it was so, both she and Natalia would be telling the truth, and Raymond would be lying, which doesn't meet the requirements. Therefore, Raymond is telling the truth, Kelly and Natalia are both lying, and Natalia is the one stealing the documents.
Riddle:
Irene and her friend Mark were walking down the street when they saw two houses. Mark wanted to play a game with Irene. He said, "One family lives in each house. And each family has two pets: either dogs or cats. The first family has a dog who likes dry food, while the other pet likes canned food. The second family has a 6-year-old dog and a newborn pet. If you can guess which family has a cat, I'll take you out for lunch." Irene manages to get the riddle right, and the two of them go out for lunch. Which family did she choose?
Answer: Irene chose the first family. There are three different possibilities for the pets that the first family has: 1) an older dog and a younger cat; 2) a younger dog, and an older cat, and; 3) two dogs. Two of these options involve a cat, and all of them are equally possible, so the chance of the first family having a cat is 2/3. There are two different possibilities for the pets that the second family has: 1) a 6-year-old dog and a newborn dog, and; 2) a 6-year-old dog and a newborn cat. One of these options involves a cat, and both of them are equally possible, so the chance of the second family having a cat is 1/2. Irene's odds of winning will be higher if she chooses the first family.

Riddle:
Simon and Bryce are two farmers. They want to see which of their chickens will lay more eggs in a month. Simon has four roosters; he claims that they can each lay 3 eggs in a day. Bryce has three hens; he claims that they can each lay 2 eggs in a day. The contest the two farmers propose happens in June. By the end of the month, which farmer will have the most eggs?
Answer: Bryce will have more eggs than Simon, simply because Simon is lying. Roosters don't lay eggs, so Simon will not have any eggs by the end of June.

" Deborah says," I was swimming in the hotel swimming pool." Who is the robber?

Riddle:
Miya had a birthday party. She invited three friends over-Derek, Trevor, and Amanda-who each gave her some gifts. In the middle of the party, Miya realizes that someone has stolen all of her gifts. She thinks it is one of the guests, so she questions them. Each guest makes two assertions-one truth and one lie. Derek: "I wasn't in the house when it happened. I know Amanda stole the gifts". Trevor: "Amanda stole them, I saw them. I already have enough gifts". Amanda: "I didn't steal the gifts. Derek tells the truth, he wasn't in the house". Who stole the gifts?
Answer: Trevor stole the gifts. If Derek was the thief, both of his assertions would have been false. And if Amanda was the thief, both of Derek's assertions would have been true. Both cases go against the rules, so Trevor is the thief.

Riddle:
Helen went to a summer camp with her best friends. One day, the friends had to tell each other fun facts about themselves. Helen told her friends, "I was born on February 29th, so I have four times fewer birthdays than you guys. This year, I turned 17,". Helen's friends laughed at her and called her out for lying. Why?
Answer: February 29th only happens once every four years. Helen couldn't celebrate her 17th birthday on her actual birthday because this number can't be divided by four. So, either she wasn't born on February 29th, or she's not 17.

Riddle:
Sofia is a student in high school. Her professor, Ms. Davis, assigned her an essay that would be due in three days. Sofia, being the worst student in her class, procrastinates and doesn't even begin the essay. Three days later, Sofia begs Ms. Davis to push the essay date back by five more days, and Ms. Davis agrees. Five days go by, and still…no essay. Sofia begs Ms. Davis to push the essay date back by a week, and Ms. Davis agrees. One week later, Sofia comes to the class with a burning candle (How did she even bring it in there?), but no essay. Sofia asks Ms. Davis if she can push the essay back until the candle wick burns out, and Ms. Davis agrees once again. Sofia laughs because she doesn't have to ever worry about the essay again. Why?
Answer: Sofia blew out the candle. She said, "until the candle wick burns out", NOT, "until the flame burns out". Therefore, Sofia can keep the candle unburned forever and never submit her essay.
Riddle:
Janet is a janitor of a large museum. One day, while cleaning the ladies' room, she spots a precious ring with red gems. When Janet leaves the ladies' room, three people–Sarah, Catherine, and Harold–show up to claim it. Sarah said that the ring belonged to her grandmother; emeralds fit her green eyes perfectly anyway. Catherine asked if the ring had an engraving etched inside, and if it was damaged in any way. Harold said that he lost the ring while washing his hands; he was going to propose to his girlfriend in a few days. Janet decided that the ring belonged to Catherine. Why?
Answer: If the ring belonged to Sarah, then she wouldn't have mentioned emeralds, because the stones on the ring are red, not green. And Harold wouldn't have been allowed in the ladies' room. Catherine was the only one who knew about the engraving on the ring, as well as how precious it is, so the ring must be hers.
Riddle:
Paul called his detective friend to report a theft. The man suspected his neighbor, Ms. Andrews, whom he thought stole his favorite figure. Paul said, "I was vacuum cleaning my room upstairs when I heard footsteps downstairs. I ran downstairs in time to see Ms. Andrews running away with my figure,". Ms. Andrews denied everything. Who should the detective believe?
Answer: The detective should believe Ms. Andrews. Vacuum cleaners are usually very noisy, so Paul couldn't possibly hear anything, let alone any footsteps.

Riddle:
One afternoon, Aaron, a cashier at a huge grocery store, called the police to report a robbery. He said that right above him, the fluorescent light started to malfunction, so he grabbed a chair to stand on while trying to fix it. As soon as Aaron touched the bulb, he burned his hand and fell down. And when he came to his senses, the money was gone. The police officer refused to investigate further. Why?
Answer: Aaron couldn't have burned his hand because fluorescent light bulbs don't heat up. Therefore, his story is fake.
Riddle:
Robert and Emma are a couple living together. Robert is rich, while Emma is broke. One day, Robert places a $50 bill on the table in their living room and leaves to go to the bathroom. Emma sees the bill and takes it for herself. When Robert comes back, he doesn't see the $50 bill; he asks Emma what happened. The woman said that a gust of wind had blown into the room and the bill flew out of the window. Robert didn't believe Emma and asked her to give him the money back. Why?
Answer: If a gust of wind flies into a room, nothing can possibly fly out of the window. The $50 bill would have just flown from the table to the floor, not the other way around.
