hangman
Hangman is a game where you guess a word by its letters. If you picked a letter that is in the word, that letter in the word will appear in its position. If not, a part of the man will be drawn. If the whole man is drawn, you lose. The goal is to guess the whole word without the whole man drawn.
Example:
XXXXXX sucks at hangman.
