The first five letters are safe.So if someone guesses wrong,theyre not hanged.After that,any wrong letter means a person is hanged.Whenever someone is hanged(wheter because he guessed the wrong word,or a letter),a new safe letter is awarded.Safe letter are granted after a hanging,not after the guess.So if there are two wrong guesses in a row,it means a double hanging and two safe letters.I hope this helps.
A triple post?TT,youve outdone yourself this time
