A good game of twister will have the Hen-Partiers in hysterics. Get a game in any toy store, or on eBay to save some money.
Bring Pictionary to a self-catering hen party and pass an afternoon laughing. Trivial Pursuit with prizes will suit the competitive Hen-Partiers and Scrabble, often overlooked, can be modified to include ex-boyfriends for extra points.
Home karaoke kits are a ticket for a self-catering Hen Party. If you don’t own a games console just borrow one and rent the Karaoke game from any video shop.
Borrow or buy a set of boules. Each team gets two metal balls, someone throws a separate smaller ball a short distance away. Then each team gets a chance to throw their ball (boule) at the smaller ball (the jack). Hysterical for the competitive gang!
