When you play treasure hunt with all adults, you usually do this at a dinner party. While the guests are waiting for their food to be prepared, you can have them play a treasure hunt dinner party game. Usually these types of games are called murder mystery parties, but they can be treasure hunt games as well. Whatever you choose the prize to be is up to you, but I found that gift cards to great places, like Best Buy or the ever popular Wal-Mart, work very well. This really is a fun way to kill time, and if you can some how get a story to go along with your treasure hunt game, then it is even that much better. If you have never tried one of these games, you should give it a go. I know this does not sound like a game that many adults would play anymore, but I think that is just because people will not give it a try. I found that people really enjoy it, and ask me to do dinner parties all the time. In fact, I usually try and have a whole theme that goes with the treasure hunt. By that I usually try and get my guest to dress up, and make the prize something related to theme. Say, if we were doing a Mob theme, then I would have everyone dress up in suites, like they were in the Mob. I would have the girls dress up in long dress, just like back in the old days. Then I may cook up some type of pasta food, and maybe my gift card would be to the Olive Garden.
I really think that you would love the treasure hunt game, if you give it a try. If you do not want to do a treasure hunt game, at least try a game that is in that category. By that I mean, play a game where you leave clues around the house for people to find. This is a game that can help spice up a normal day of some type. I know that after you give it a shot, you are going to love it. I know when I first did it, I was a little scared to try it, but know I love it.
