Every question mark can be replaced with the number 6.

6 + 6 + 6 + 6 + 6 = 30

There are a total of 40 squares. Did you spot them all? If not, just try again.

If you thought that pattern C forms a full house when folded along the dotted lines, then you are right.

It's charcoal, duh!

A, B, C, or D? 

... The only correct answer is C!

Believe it or not, we even had to try it ourself, and the only piece that fits is C.

Oops! This question cannot be solved mathematically. Why you ask? Because the sum of three odd numbers cannot be even. 

We hope your brain didn't go up in smoke trying to

solve this brain teaser!

Totally different, and much more challenging than counting squares. There are a whooping 26 triangles in this image. Did you find them? If not, try again. 

The reciprocal squares will be: yellow & pink, turquoise & green, and orange & lavender. 

Did you get it right? 

After turning the clock 90° counterclockwise, the time will be 12:20. 

Did you get it right without rotating your entire screen? 

If Frank's father has 5 sons and the names of 4 sons are Fefe, Fifi, Fofo, Fufu, then Frank is the 5th son!

Were you able to find the the mistake? If not, maybe check again again?

The word "the" was written twice!

We don't want to waste valuable water, or we would show you. But just take our word for it, that tank number 2 will fill first. 

The bus is traveling left! Why? Because you can't see a door. 

And because you know it's traveling on the Interstate Highway, you know it's an American bus where the driver

sits on the left-hand side.

We love all the circles, but A is the correct answer. Sorry, other circles. 

You are looking to find the following 3 values: Circle = 3, Star = 5, Triangle = 4. 

If you got it right, take one of the five stars home with you. 

The correct answer is 16! To prove to you that we didn't make it up, here is a totally mathematical explanation. Starting bottom left and moving clockwise around the triangle,

the numbers follow a sequence. 1x1=1, 2x2=4, 3x3=9, therefore 4x4 is what replaces the question mark, and the pattern keeps going up to 9x9. Cool, huh?

If you rotate these around a few times, B, C, and D can all line up on top of one another, but A is the odd one out.

If you guessed square B, then you are right! 

There is a total of 47 "E"s, can you beeeeeeeeeelieve it?

The arrow should point downwards, or south for that matter! 

And here is why! If you start from the top-left corner and spiral clockwise, the series goes as follows: south,

east, north, south, west, east. Following that pattern, south is the answer!

Simply place the Xs in the 8, 9, 6 and 4, 1, 2 squares. Voilà, you are now a master at losing in tic-tac-toe!

If you counted correctly, your answer will be 12!

Okay, maybe it was not that difficult. This pyramid holds a total of 30 balls. 

For the people who will ask "BUT HOW???" here is the explanation:
The bottom level has

a 4x4 arrangement (16 balls). 
Above that, there's a 3x3 arrangement (9 balls).
Above that, you can see a 2x2 (4 balls).
Then, there is 1 ball on top.

16 + 9 +

4 + 1 = 30

To fix it, simply take the vertical pick from the plus sign to turn the 6 into an 8. Tadaaa! 8 – 4 = 4, right?

The correct answer is 19. Did you find them all?

Here is the full breakdown. An apple is worth 10 and a bunch of four bananas is worth 4. You still following? A coconut must equal 2. If you eat

half of a coconut it's only worth 1, and after munching one of the 4 bananas, the three bananas left are worth 3. Add those to your apple (which was

10, in case you've forgotten). The answer is 14. 

Simply spell the word TEN in capital letters. Unless you are magician, this is the only solution.

The answer is 3. Did you get it right?

Each number is the sum of the number that is directly above it plus the number directly to the right.

Figure A has the maximum painted area. 

Did you pick LETTUCE? Because If you take the first letter of each of the other seven words and place it at the end, it will spell out the same

word backwards. Bet you didn't know that before!

The correct answer is 9! 

Pat yourself on the shoulder if you got it right. 

Pour the second glass from the left into the empty glass second from the right. Pretty clever, we must admit.

The answer is C. 

The only answer is D, and here is why. Each line contains two red dice, and only one blue die. Each line contains a two, a three and a five.

Therefore the missing die must be a red die, of the number three.

All the doors will lead outside. But Door B is different from all the others!

In order to hit 100, you'll need a total of 6 darts. 

Make sure you are hitting 17, 17, 17, 17, 16, and 16.
