One player starts by placing the bottle in the center of the circle and spinning it. The neck of the bottle determines who is "It."
Before anyone asks "Truth or Dare?" you lay down the law.
In a Full game, players should have a one-time use "Double Down" card (or token). If they choose Truth, but hate the question, they can Double Down. This forces the asker to change it to a Dare. However , if they Double Down, the Dare automatically becomes "Double or Nothing"—meaning the dare will be significantly harder than a standard dare.
