Option [+3]

This one requires a group of friends (minimum 1 friend but more is better). At the start of the night, all take a piece of paper and write a challenge which can be reasonable completed in 1 day and then fold the paper and put them in a hat. Then you and your friends should play a game(s) and the overall winner doesn't have to pull a slip of paper from a hat, everyone else has too and must perform the challenge. This game doesn't have to be 18+, the maturity of the game depends entirely on the challenges and games played.

quick notes -

• make sure all players have agreed before hand of what everyone is comfortable with challenge wise.
• The person who wrote the challenge should supply any equipment required to complete the challenge.
