We’ll do some more themed Brain Games in the future, but today, something easy on the ol’ noggin:

What odd number becomes even
when one letter is removed?

HERE is the solution.

  1. I think your solution should read: Remove the “S” and you have “even.”

    Great riddle!

  2. Fun fun! It kinda got me, though I do have a point!

    My guess was 11. When you remove L it also becomes Even.

    ELEVEN – L (Pronounced “EL”) = EVEN

    : )

  3. Oddly enough VII less one letter is VI so seven works in a variety of ways.

  4. This applies to a lot of roman numerals too. For example, removing the I from IX or XI will result in X, which is an even number.

  5. Yep, Kev! I figured someone might say SIX, since SIX – S = IX, the Roman numeral for nine.

  6. Wow you were easy on the brain today, that was my first guess.

  7. I had two ideas and wasn’t sure which one you were going for…the answer that you gave and zero…

    none – n = one. None is technically even, I believe.

    Then I thought of Seven and figured that was more likely.

  8. This was great! What fun :)
