Welcome to Hangman... a guessing game that can be played by two or
more players.

In this version, the computer will set a secret word and you (the
players) will have tries to guess it by suggesting letters within a
certain number of guesses.

This game tests your vocabulary. Make sure you crack it before the
poor stick figure meets its doom :-D
