Letter Riddles are simply stated riddles with solutions that are letters. For example:

What two letters are a girl's name?

There are multiple answers, like KT as in Katie, ME as in Emmie or GG as in Gigi. When you say the letters you get the name!

Here are five for you to try - Good Luck!

What two letters are sometimes poison?
What two letters are jealous?
What two letters are too much?
What two letters are not hard?
What two letters are some?

In each puzzle, a word or words are missing, replaced by their first letter. To solve each puzzle, you need to find the missing words. Here’s an example of how they work:

example: 12 I in a F     has solution     12 INCHES in a FOOT

1 W on a U
2 N in a D
3 F in a Y
4 S in a D of C
5 O in the W
6 F on a C
SW and the 7 D
8 L on an O
9 L of a C
10 Y in a D

In the game SET, each card has four attributes - color, shape, number and fill. A set is comprised of 3 cards in which each attribute is all the same or all different across all 3 cards.

The rule is "IF two are the same is one is different, THEN it's NOT a SET!"

This is a set the colors are all different the shapes are all different the numbers are all the same the fills are all different		This is NOT a set the numbers are all different but there are ... two greens and one purple two ovals and one diamond one solid and two empty fills

Can you find 12 sets in the following nine cards? Click on a card to select it! You will be automatically scored and order does not matter!

1.	2.	3.	4.
5.	6.	7.	8.
9.	10.	11.	12.

1					2
3					4

Alphametics are puzzles that use simple arimetic in which letters represent unique single digit numbers. The trick is to determine the number to which each letter corresponds. Below there are eight distinct letters, O, N, E, T, W, F, U and R. Use the numbers 0 through 9 (two of which will NOT be used) to solve the puzzle.

Today’s puzzle is a counting puzzle. The objective is to count the number of squares in each figure. After completing all three puzzles, select Check to see if you're right! Although this looks simple, this may prove to be more challenging than it looks.

As a hint, the number of squares in the Puzzle 1 is NOT 4!
Good Luck!

Use each of the numbers 2, 4, 6 and 8 once and only once along with any combination of the arithmetic operators + - * / and at most one set of parenthesis ( ) to make each number 1 through 10.

For example, here are two ways to make the number 10

8 * 4 / 2 - 6 and (8 - 6) * 4 + 2

answers may be one-digit or two-digit numbers

an even number		a power of 2		a power of 3		a prime number
a prime with prime digits whose sum is prime		a power of 5		a power of 7		the product of two primes

helpful information
primes = {2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97}

powers of 3 = {1,3,9,27,81}
powers of 5 = {1,5,25}
powers of 7 = {1,7,49}
0 is an even number!

Just like in Day 3, in each puzzle a word or words are missing, replaced by their first letter. To solve each puzzle, you need to find the missing words. Here’s an example of how they work:

example: 12 I in a F     has solution     12 INCHES in a FOOT

2 P in a P
2 H in a W
3 A in a T
4 ES in a S
5 F on each H
7 D in a W
10 D in a D
12 M in a Y
60 M in an H
A the W in 80 D

Using the numbers 1,2,3,4,5,6,7,8 and 9 once and only once,
use the clues below to solve the puzzle.

1. the center row contains only even numbers

2. the bottom row contains only odd numbers

3. 4 is in the top row

4. the top row contains the smallest number in each column

5. 2 is in the center circle

6. the center column contains the smallest number in each row

7. the left column contains only multiples of 3

Answer each of the following questions so that all are correct!

1. How many questions have an odd solution?		1		2		3		4
2. How many questions have an even solution?		1		2		3		4
3. How many questions have 1 as the solution?		1		2		3		4
4. How many questions have 2 as the solution?		1		2		3		4
5. How many questions have 3 as the solution?		1		2		3		4
6. How many questions have 4 as the solution?		1		2		3		4

Answer each with number or a single word!

Good Luck!

Just like in Days 3 and 10, in each puzzle a word or words are missing, replaced by their first letter. To solve each puzzle, you need to find the missing words. Here’s an example of how they work:

example: 12 I in a F     has solution     12 INCHES in a FOOT

3 P for a FG
3 WK
3 LP and the BBW
3 S (M, L and C)
3 H on a T
GL and the 3 B
3 W on a T
3 is a C
3 BM
3 FH

Use each of the numbers 2, 3, 5 and 8 once and only once along with any combination of the arithmetic operators + - * / and at most one set of parenthesis ( ) to make each number 1 through 10.

For example, here are two ways to make the number 4

8 - (5 + 3) / 2 and 8 - 5 + 3 - 2
