Ah, the end of the week, and it's time for Free-for-All Friday here at the mentalfloss.com Brain Game. Good luck!

This week, little Susan just learned to count from 1 to 10 orally.

Susan doesn't mind the numbers 3, 5, 7, 9, and 10,
but she does NOT like the numbers 1, 2, 4, 6, and 8.

What factor distinguishes the numbers that Susan does NOT like?

Here is my SOLUTION.

MY SOLUTION:

The numbers Susan dislikes have homophones (words pronounced the same but with a different spelling and meaning).

1 = won
2 = too
4 = for
6 = sics
8 = ate

The other numbers (3, 5, 7, 9, and 10) do not have homophones. (10 = tin is close, but the vowel is pronounced in a slightly different way.)

NOTE: These types of puzzles often have alternate correct answers. (Just because yours didn't match mine doesn't mean that your answer is wrong!) If you came up with one that you feel is right, please add it to the comments. Thanks, and have a great weekend!
