Free Printable Brain Teasers With Answers

Here are ten free printable brain teasers with answers, categorized by difficulty level. Whether you're a beginner or an experienced puzzle solver, there's something for everyone.

Easy Brain Teasers

1. The Three Switches

   • You are standing in a room with three light switches. Each switch corresponds to one of three light bulbs in a room. Each light bulb is either on or off. You can turn the lights on and off as many times as you want, but you can only enter the room one time to observe the light bulbs. How can you figure out which switch controls which light bulb?

   Answer: Turn switch 1 to the "on" position for 5 minutes. Then, turn it off and turn switch 2 to the "on" position. Immediately enter the room and observe the light bulbs. The bulb that is on is controlled by switch 2. The bulb that is warm (but off) is controlled by switch 1. The remaining bulb is controlled by switch 3.

2. The Five Hats

   • Five people are wearing hats, and each hat is either white or black. Each person can see the hats of the other four people, but not their own. How can the people figure out what color their own hat is?

   Answer: The people can figure out the color of their hat by using a process of elimination. Each person looks at the other four people and counts how many white and black hats they see. If a person sees an equal number of white and black hats, they know their own hat is black. If they see more white hats than black hats, they know their own hat is white.

3. The River Crossing

   • A farmer needs to cross a river with a wolf, a goat, and a cabbage. He has a small boat that can only hold himself and one of the three items. If the wolf is left alone with the goat, the wolf will eat the goat. If the goat is left alone with the cabbage, the goat will eat the cabbage. How can the farmer get everything across the river safely?

   Answer: The farmer takes the goat across the river first and leaves it on the other side. Then, he goes back to the original side and picks up the cabbage. He takes the cabbage across the river and leaves it on the other side with the goat. However, he takes the goat back to the original side. Next, he picks up the wolf and takes it across the river, leaving it on the other side with the cabbage. Finally, he goes back to the original side and picks up the goat, taking it across the river to join the wolf and the cabbage.

4. The Mysterious Temple

   • You are standing in front of a mysterious temple with two doors. One door leads to certain death, and the other door leads to freedom. However, the doors are identical, and there is no label or sign on either door. There is a guard standing in front of each door, but one guard always tells the truth, and the other guard always lies. You can ask one question to one guard to figure out which door leads to freedom. What question should you ask?

   Answer: You should ask one of the guards, "If I were to ask the other guard which door leads to freedom, what would they say?" Think about it for a moment. If you ask the truth-telling guard, they will tell you that the lying guard would point to the door that leads to death. If you ask the lying guard, they will lie about what the truth-telling guard would say, and they will also point to the door that leads to death. So, regardless of the answer, you can safely assume the opposite door leads to freedom.

5. The Hardest Logic Puzzle Ever

   • There are five houses in a row, each painted a different color: blue, green, red, white, and yellow. Each house is occupied by a person of a different nationality: American, British, Canadian, Indian, and Japanese. Each person has a different favorite drink: coffee, tea, milk, soda, and water. Using the following clues, can you determine the color of each house, the nationality of its occupant, and their favorite drink?

   Clues:

   • The Canadian lives in the first house.
   • The person who drinks milk lives next to the person who owns the yellow house.
   • The person who owns the yellow house drinks soda.
   • The British person lives in the red house.
   • The person who drinks coffee lives in the house next to the British person.
   • The American lives in the house next to the person who drinks tea.

   Answer: This puzzle requires careful analysis of the clues and a process of elimination. The solution is as follows:

   • House 1: Yellow, Canadian, milk
   • House 2: Blue, American, coffee
   • House 3: Red, British, tea
   • House 4: Green, Indian, water
   • House 5: White, Japanese, soda

6. The Prisoners and the Hats

   • One hundred prisoners are arrested and put in individual cells. The warden gives each prisoner a hat to wear, and the hats are either white or black. The prisoners can see the hats of the other prisoners, but not their own. The warden tells the prisoners that if any prisoner can figure out the color of their own hat, all the prisoners will be set free. However, if any prisoner incorrectly guesses the color of their hat, all the prisoners will be executed. The prisoners are not allowed to communicate with each other in any way. How can the prisoners figure out the color of their own hats?

   Answer: This puzzle requires a clever strategy. Each prisoner should look at the hats of the other 99 prisoners. If a prisoner sees an odd number of white hats, they know their own hat is black. If a prisoner sees an even number of white hats, they know their own hat is white. This solution works because the total number of white hats is either odd or even. If the total number of white hats is odd, the prisoners who see an odd number of white hats will correctly guess that their own hat is black. If the total number of white hats is even, the prisoners who see an even number of white hats will correctly guess that their own hat is white.

7. The Counterfeit Coin

   • You have eight coins, and one of them is counterfeit. The counterfeit coin weighs slightly less than the real coins. How can you use a balance scale and only two weighings to identify the counterfeit coin?

   Answer: Weigh four coins against four coins. If one side is lighter, the counterfeit coin is one of those four. Weigh three of those four coins against each other. If one side is lighter, the counterfeit coin is one of those three. If the two sides are balanced, the remaining coin is counterfeit.

8. The Water Bottles

   • You have three water bottles, one of which can hold 3 liters, one of which can hold 5 liters, and one of which can hold 8 liters. How can you measure exactly 4 liters of water using only these three bottles?

   Answer: Fill the 5-liter bottle completely and pour it into the 8-liter bottle. Fill the 5-liter bottle again and pour it into the 3-liter bottle until the 3-liter bottle is full, leaving 2 liters remaining in the 5-liter bottle. Empty the 3-liter bottle and pour the remaining 2 liters from the 5-liter bottle into the 3-liter bottle. Fill the 5-liter bottle again and pour it into the 8-liter bottle until the 8-liter bottle is full, leaving 2 liters remaining in the 5-liter bottle. Empty the 8-liter bottle and pour the remaining 2 liters from the 5-liter bottle into the 8-liter bottle. Fill the 3-liter bottle and pour it into the 5-liter bottle. Now, the 5-liter bottle contains 4 liters of water.
