How to play the game?
The first person who post must have three or two letters for next ten players or less to figure out the answer. On eleventh post when there's no right answer, the first player wins. Any person who reply on thirteenth post have to post next few letters for friends to decipher the meaning. The post doesn't have to be twelfth, it can be less.
If one of friends crack the first person's code, it's her or his turn to give three letters or pass turn to any second player.
~First person give code, one of friends crack it. One of them give code afterwards and so on.~
Here's the rules of game
Don't spam on each post, because each post takes one chance of twelve turns. Be wise when you post here!
Don't make game difficult over the top. No hints, there are only two or three words for twelve person to decipher.
Do not reused the code until at least 20 code have been cracked before hand.
If the person who post question has not post here to confirm answer, required to tell one of friends the answer by sending message in two day's notice. He or she take over to confirm the answer on third day. This rule apply when the person realize he or she has to be absent for a week.
