The Three Keys and Three Doors:

Imagine facing three doors, each with a unique key. How many attempts will it take to figure out the correct key for each door? If you're terrible at guessing, you'll need six attempts. Let's break it down: three attempts for three doors with key two, two attempts for two doors with key three, and one attempt for the last door. Can you crack the code with the fewest attempts?

Chain Link Challenge:

You have five pieces of chain, each made up of three links. Your task is to create a long chain using these pieces, but there's a catch. Welding an open link costs three dollars, and breaking a link open costs one dollar. Can you create the long chain with a budget of only fifteen dollars?

Decoding the Equation:

Can you decipher the pattern in the equation? Four plus two equals twenty-six, eight plus one equals seventy-nine, six plus five equals one hundred and eleven. The correct answer is fourteen. Each letter is worth two points. Now, can you write eleven thousand, one hundred, and eleven in digits?

Crossing the River:

Nine numbers from one to nine need to cross a river. However, the boat can only carry three numbers at a time, and the sum of the traveling numbers must be a square number. How many trips will it take for all the numbers to cross the river?

You are presented with a three-digit number riddle. The second digit is four times larger than the first digit, and the third digit is three less than the second digit. Can you crack the code and identify the number? The answer is 141. The second digit, 4, is four times larger than the first digit, 1, and the third digit, 1, is three less than the second digit.

The Growing Lily:

Imagine a beautiful water lily growing in a tiny pond. The flower doubles in size every day, and you know that in ten days, it will cover the entire pond. But in how many days will the lily cover half of the pond? Surprisingly, it will happen on the ninth day. Since the lily doubles in size every day, it will cover half of the pond one day before it covers the entire pond.

The Matchstick Equation:

You are presented with an equation made from matchsticks: six plus four equals four. Your task is to make the equation true by moving just one matchstick. The solution is to take one matchstick from the plus sign and add it to six, creating eight minus four equals four.

The Hardware Store Mystery:

A man walks into a hardware store and asks the price of various items. He is given a peculiar pricing scheme: one item costs one dollar, eight items cost two dollars, thirteen items cost three dollars, and four thousand nine hundred and eighty-six items cost four dollars. Can you figure out what the man wanted to buy? The answer is door numbers. The prices correspond to the number of letters in each word: one (3 letters), eight (5 letters), thirteen (8 letters), and four thousand nine hundred and eighty-six (4 letters).
