Click start and guess the word. A-er means that the word comes before your answer in alphabetical order. Z-er means that the word comes after your answer in alphabetical order. The word is always between the "Top" and "Bottom" variables. When you guess correctly, the game should restart with a different word, but the first question on a new word doesn't work for some reason.
This project currently has 32 possible words, 3 of them are not real.
