Your goal is to spell out the word the computer is thinking of. Each letter in the word is represented by an underscore. Guess letters by typing them and they will appear where they would in the word.
There is a twist, though: each guess you make, the computer will change its word to another word not using any of the letters that you have guessed so far. For example, if the computer's word was "abate" and you guessed "a," it would change to another five-letter word not using the letter "a." After six failed guesses hangman is hung, but if you complete the word before that you win. Good luck.
