We have been asked by many people who read these forums not to put the solutions to the puzzles in the forums (to keep from inadvertently spoiling the game for people). We really want to give people the help that they need, so we have made it pretty easy to get exactly the kind of help you need, ranging from a private message with subtle hints (or spoilers) to a detailed strategy/puzzle guide that you can check out to get help. You can see your options
