[quote]How flexible can we get with the puzzles or traps in our room? Could we have a room with carnival where we try to throw rings onto the heads of bottles from behind a rope? [/quote]
Yes. Pretty much anything goes as long as the challenge itself is fairly presented (e.g. hidden elements need to be hinted at) and at least one viable solution is humanly doable. Were you to want the ring toss to be a part of your room, I would go on to ask about the specifics of the ring toss, such as how to allow players to make many attempts, if there is an intended method to circumvent the ring toss, or what you would like to happen if players try to mug the ring toss attendant for prizes.
