This is a kind of word puzzle.
You are given the number of letters of a word to be guessed.
You are allowed to ask a mystery-word-giver some questions
in order to get clues for the word. But the number of the questions
are limited. Every time you get a reply, "No", one body part of a hangman
- left and right arms, left and right legs, and a head - are drawn.
If you can get the correct word, before your hangman is hanged,
you win. You get one point. Otherwise you are out! The giver get one point.
We made four teams, and competed by team.
