100 Likes: 500 Likes Puzzle: Hint 5

The final hint is here! I'm not letting you get away easily, either...

You must use the answers to the other Hints to figure out this one. You get one clue. Numbers in brackets [] represent letters in some way.


Hint 1: [1] minus 1

Hint 2: [5] plus 3

Hint 3: [4]

Hint 4: [3] minus 3

You should have gotten 4 letters at this point. There is a fifth letter, which is the only vowel that did not appear in the other Hints.

Good luck. You'll all need it.
