# Top 10 Hardest Riddles In The World With Answers

Riddles have been a part of human culture for centuries. They challenge our thinking, test our problem-solving skills, and often leave us scratching our heads in frustration. While some riddles are relatively easy to solve, others can be incredibly difficult and require a great deal of mental effort. In this article, we will explore the top 10 hardest riddles in the world, along with their answers, and delve into the fascinating world of riddles.

## 1. The Monty Hall Problem

The Monty Hall Problem is a famous probability puzzle named after the host of the television game show “Let’s Make a Deal,” Monty Hall. The puzzle goes as follows:

You are a contestant on a game show. There are three doors in front of you. Behind one door is a car, and behind the other two doors are goats. You choose one door, let’s say Door 1. The host, Monty Hall, who knows what is behind each door, opens another door, revealing a goat behind it (let’s say Door 3). Now, Monty gives you a choice: stick with your original choice (Door 1) or switch to the remaining unopened door (Door 2). What should you do to maximize your chances of winning the car?

The answer to this riddle may seem counterintuitive, but statistically, you should switch to the remaining unopened door (Door 2). By doing so, your chances of winning the car increase from 1/3 to 2/3.

## 2. The Two Envelopes Problem

The Two Envelopes Problem is a classic riddle that challenges our intuition about probability. The riddle goes as follows:

You are given two indistinguishable envelopes, each containing money. One envelope has twice the amount of money as the other. You randomly choose one envelope and open it, revealing a certain amount of money. Now, you have the option to stick with the opened envelope or switch to the other unopened envelope. What should you do to maximize your expected winnings?

The answer to this riddle is that it doesn’t matter whether you stick with the opened envelope or switch to the other one. The expected value of both envelopes is the same, so there is no advantage to switching.

## 3. The Hardest Logic Puzzle Ever

The Hardest Logic Puzzle Ever, also known as “The Green-Eyed Logic Puzzle,” is a riddle that requires logical reasoning and deduction. The puzzle goes as follows:

In a remote island, there are 100 people, 99 of whom have green eyes, and one person has blue eyes. The islanders can only see the eye color of others but cannot communicate or leave the island. They are not aware of their own eye color. A visitor arrives on the island and announces that at least one person has blue eyes. The visitor also states that if any islander discovers their own eye color, they must leave the island at dawn. How many days will it take for all the blue-eyed people to leave the island?

The answer to this riddle is that it will take 100 days for all the blue-eyed people to leave the island. Each blue-eyed person will realize that they are the only one with blue eyes after observing that no one else is leaving. Therefore, on the 100th day, all the blue-eyed people will leave the island.

## 4. The Hardest Math Problem

The Hardest Math Problem is a riddle that combines mathematical concepts and logical reasoning. The problem goes as follows:

What is the next number in the sequence: 8, 5, 4, 9, 1, 7, 6, 10, 3, 2, ?

The answer to this riddle is 11. The sequence is based on the number of letters in the spelling of each number (eight, five, four, nine, one, seven, six, ten, three, two). Therefore, the next number in the sequence is eleven, which has six letters.

## 5. The Hardest Word Riddle

The Hardest Word Riddle challenges our ability to think outside the box and find alternative meanings for words. The riddle goes as follows:

What word becomes shorter when you add two letters to it?

The answer to this riddle is “short.” When you add the letters “er” to the word “short,” it becomes “shorter,” which is a longer word.

## 6. The Hardest Logic Grid Puzzle

The Hardest Logic Grid Puzzle is a riddle that requires logical deduction and careful analysis of given clues. The puzzle goes as follows:

Five friends (Alice, Bob, Claire, David, and Emily) are sitting in a row. Each friend is wearing a different color shirt (red, blue, green, yellow, and orange) and has a different favorite food (pizza, pasta, sushi, burgers, and tacos). Can you determine the color of each friend’s shirt and their favorite food based on the following clues?

- Alice is sitting next to the person wearing the red shirt.
- Bob’s favorite food is sushi.
