Some fun games to play with friends include Wink Murder, Continuing Novel and Partners in Pen. These simple games require minimal materials and are both quick and easy to play.
Wink Murder is a classic game in which one player, randomly designated as the murderer, "kills" other players by winking at them. Another player, designated as the detective, must attempt to discover who the murderer is. After two successful murders, the detective must make a guess as to the murderer's identity. If the detective guesses correctly, he wins the game. Otherwise, the murderer gets away.
Continuing Novel is a collaborative game that allows players to exercise their creativity. After the group chooses a theme, one player starts out by writing a six-line story on a pad of paper. That player then passes the paper on to the next player, who can only look at the final line before continuing the story. After the paper has made its way to everyone, players can take turns reading the results out loud.
Partners in Pen has players divide up into teams of two and sit with their backs to each other. One player holds a random object and attempts to describe it to the other player without saying specifically what it is or what it's used for. The other player attempts to draw the item on a piece of paper, with inevitably interesting results.
