In some cases, this could be the first meeting involving the two families or groups of friends and any icebreaker function will be a pleasant event.
During that light, whoever manages the engagement party (likely the bride's family, but it can be the engaged couple or others who wants to plan the party) should prepare a few games and activities made to help everyone become familiar with all the others.
Firstly is a trivia game.
Come up with a "Trivial Pursuit" type game with questions about the bride and groom's lives.
You might keep the questions to just truths and events relating to both the groom and bride (such as "How much time did it take her to say "yes" when he asked","Where did he pop the question", where did they meet, etc), or you can include questions pertaining to their lives outside of each other and before they met each other.
Not only can this be fun, but also it's an entertaining way for people to become familiar with each other and the engaged couple better.
One popular icebreaker that's used at business gatherings and company parties can also perform really well at engagement parties.
Tape a card to each person's back and motivate him or her to survey the room, associate with everyone and particularly attempt to get to know someone they have certainly not met before.
Before getting to someone else, you'll want to make a remark about the person on the card on his or her back.
Party-goers write an idea of that person, such as "she seems sweet" or "he knows a lot about the weather".
This icebreaker ends as soon as the interacting session is over.
The cards are then read one by one and people not only become familiar with each other better, but have fun with reading all the remarks people put together about them.
Aim to ensure that comments are complimentary or somehow presented in a favorable light.
Hurtful opinions, obviously, are not applicable.
If this is truly the first-time many of the guests have met, then another fun game involving the wearing of cards might be in order.
In this game, each guest wears a card on their front that has their name on the front and a number on the back.
They don't show to anyone what their number is.
Guests entertain and chat and get acquainted with each other over the course of the evening.
Toward the finale of the evening, the cards are flipped over and the number side is shown.
Everyone gets a small note and writes the numbers on the paper, then tries to designate the name of someone with their number.
This fun game can be hard for people who are bad with names, but it's fun nonetheless.
For a procedure that doesn't put people on the spot quite so much, consider letting the already marrieds help out the to-be marrieds.
Place two pieces of poster board on the wall and mark them "advice from women" and "advice from men".
This is the time to offer advice about wedding planning, not about being married.
That advice can come later.
Inspire guests to offer their own wedding planning advice where the recommendation from seniors at the party could be different from the younger couples in the group, making enlightening group of comments.
