Spin the Bottle
Basically, what you do is, you take a bottle (or something like that) and sit in a circle with your guests.
Somebody spins the bottle and whoever it lands on, has to walk out of the room and wait until the rest of the people decide what dare to give them.
Then, when they have decided what to give them, the others call them back into the room and gives them the dare.
If they do not want to do it they are either out, or they do another dare and if they do not want to do the second dare, then they are out without a choice.
Eventually, there will be one person left. that person will be the DAREDEVIL.
And then, finally,that DAREDEVIL dare's everyone else to do a dare without a choice. he then gets a prize. (optional)
