The idea is to answer a question left by previous player, and then use one of the letters contained in the answer you have given (ideally not the first letter), and use this to ask the next question. For instance a previous player may have said,Name a colour starting with B (would be a few alternatives) My answer is Blue (I am now choosing to use L, U, or E for my next question, I'll opt for (E)
Name a feature belonging to your head/face beginning with E
