40th Birthday Party Games


Fashion Scavenger Hunt

Fashion is one aspect which changes a lot with time and it’s definitely a fun and interesting activity to go back in time, at least in the fashion sense. 

The idea here is to hunt for different clothes that represents the time when the celebrant was born or during the 40s. You can limit their hunting ground to just around the neighborhood or up to certain area of your town.

When they find the right clothes, one member of the group must “model” the clothes and have his/her picture taken with the owner of the clothes.

You can choose to set a limit of at most one set of clothes per household, which means that even if a house has tons of old fashion outfits, the group can only choose one set to model and photograph. We will also leave it to you if you will allow more than one group to model clothes from the same household.

Set a time limit and ask the group to model and photograph as much clothes as possible within the said time. The group who was able to bring back the most number of valid photos will win this hunt. If you are up to giving more prizes, then be sure to award the group’s best model or the one with the best attire. The birthday celebrant can help in the judging.

Finding Forty

This is a treasure hunt game that requires each of the group to find items that represents the magic number 40. The simplest way to prepare for this game is to stamp some special items (special to the celebrant) with the word or number 40 and hide them in different areas across the room/house.

The group with the most number of forties find will be the winning group.

Back In Time

You can use movies and music to go back in time. You can choose to just watch a classic movie or have a fun karaoke time with your friends, wherein music popular during the 40s or when the celebrant was born will be the focus.

But if you prefer to make a game out of this, then you can choose to play charade wherein classic band, music, movies are the topic. If you don’t want to act things out, then a straightforward guessing game of the music title, singer, or movie based on some prepared music or movie clips will also be fun.

Counting Forty

This is a modified version of the card game 41. On this version, the goal is to reach a number nearest to the number 40 (we’ll let you decide if having 39 and 41 means a tie or whether 41 is better or vice versa).
