This game hasn't change a lot either, but now if you don't know the answer, you can ask for a clue. Here are 4 rules written by fanfly for the other game similar to this one. Would you please take your time to read rule number 2? Guessing a season now is not enough, because it makes the game too easy to win, and well, wouldn't it be better as a challenge?
Guess what episode the quote is from.
If you don't know, you can ask for a clue. You can be specific [ie: What season is it from?] or you can just ask for a general clue. Clues are unlimited, you can keep asking until someone guesses right.
Whoever guesses the right episode posts the next quote.
Everyone who participates must check the forum daily. If someone takes longer than 4 days to respond [For example, if the winner hasn't posted a new quote or responded to tell someone whether they guessed correctly or not] a new guess can be posted by anyone.
The person who types the quote always has to add the name of the character who said such quote first so it's easier for everyone to know from which episode it the quote is.
Dean Winchester: You're like a walking encyclopedia of weirdness.
Guess from what episode and season that quote is from, and say who was Dean talking to when he said that. And yeah, I know this is easy to guess. :)
Also, what an awesome picture, huh? :D
