Hangman

Hangman - is a guessing game. Computer will generate a sentence and your job is to find all the letters in it. The sentence is randomly generated so you can expect some funny texts such as "YOUR MOTHER IS BARKING MADLY". If you miss seven letters Hangman will be hanged (no more forgiveness).

Easy: all first and last letters of the word, as well as those repeating, are revealed.
Medium: five random letters (and those repeating) are revealed.
Hard: nothing is revealed.
