Are you just looking on Gamehag for other methods to get Soul Gems? Well Don't play the guessing game! I have played it and lost all of my Soul Gems, because the guessing game is actually a way for Gamehag to earn money back and not to give you more. If you still want to play it then quit after you have won all your money back or when you have earned more then when you started, because if you don't you will end up like me without any Soul Gems. So don't do it! Don't start playing the guessing game. I hope you've learning something from this and just one other thing: DON'T PLAY THE GUESSING GAME!
