Lego Party Ideas for Invitations
Get your guests into the spirit of your party right from the start by sending some great invitations. Here are some ideas for making your own unique party invites:
Lego Puzzle Invitations — For each party guest, create a small flat square or rectangular brick out of different colored Legos or Duplos. Use a Sharpie pen to write your party information on the flat face of the brick. Break the invitation apart and send it to your guests it in a mailing tube, padded envelope, or small box. Under their address write, “Invitation to _____’s Lego Party. Some Assembly Required!”
Photo Invitations — Have your guest of honor set up a scene made out of Legos and Lego mini figures. Take a picture of the creation and glue it to a folded piece of colorful cardstock. Write your party information inside. For an extra special touch, add some LEGO stickers to the envelope.
You can always find lots of great online party invitations with a free RSVP manager at Evite,

**General Invitation Tips** — If you choose to make your own invitations, don’t forget to include the date, location, and time of your party. It is also helpful to put the host’s name, RSVP by date, and either your phone number or email.
Lego Party Ideas for Decorations
Legos come in lots of colors, but are mostly known for the traditional shades of red, yellow, green and blue. These colors make a bright and festive color scheme for a party. Here are some more of our favorite Lego theme party decoration ideas:
Start by using streamers, balloons, and tableware in primary colors.
Create a Lego-style “Happy Birthday” banner by writing each letter on a different color of construction paper and using lettering that looks like the traditional Lego font. Attach them to a piece of colored yarn or ribbon and hang across a doorway or mantle.
Create your own wall art with the classic LEGO movie quote, “Everything is Awesome!”
Use large pieces of different colored construction paper (with lightly drawn circles to look like the Lego knobs) to create a “Welcome to ____’s Lego Birthday Party!” sign. Hang it on your front door to greet your guests.
If your guest of honor is a Lego lover, chances are he has some models that he is proud of. Display these as table centerpieces or strategically placed party decorations. (Make sure they are positioned where they won’t be broken.)
Make your own giant Lego pieces by gluing the bottoms of paper cups to rectangular pieces of craft foam. Spray paint these in different colors. You can either stack them on your party serving areas or use colored ribbon to hang them at different heights from light fixtures or the ceiling.
If you are planning on having your guests do any Lego construction during your party, consider setting up a “Construction Zone” using construction cones and caution tape. You could even give the kids hard hats to wear when they are building. These also make great take home party favors!

Activities For Your Party
There are so many different types of activities that could be incorporated into a Lego theme party — there are video games, Lego party games, board games, and of course, Lego construction activities! Here are some Lego party ideas for activities to keep your guests going for a long time…
Show The LEGO Movie
Free Play — A great Lego party idea to keep everyone engaged at the start of the event while you are waiting for guests to arrive is to designate an area for free play. Set out a jumble of assorted Lego pieces and let imaginations run wild.
Designating a construction zone (mentioned above) is a fun way to set aside a part of your party area for free play.
**NOTE — A great resource for finding lots of Legos and specific pieces such as car wheels is www.bricklink.com.
Lego Guessing Jar — Another activity that works well at the start of a party is a Lego estimation jar. Fill a decorative jar with an assortment of Lego pieces and have your guests make their best estimate as to how many are in the jar. Give the full jar or a small prize to the person whose guess is the closest.
Timed Building Events — Set out a pile of Legos for the group and give them a variety of timed challenges. Some examples might include:
*Who can build the tallest tower in 2 minutes?
*Who can build the longest bridge in 5 minutes?
*Who can build the coolest home in 10 minutes?
Elect a judge and give awards to the winners.
Build and Race Cars — Give each party guest a set of Lego wheels. Set out a large variety of Lego pieces and give guests a specified amount of time to create a car. When everyone is finished, race the cars down an inclined ramp (make these out of large pieces of plywood or refrigerator boxes). Give awards to the car that went fastest, held together best, and looked the coolest.
Lego Relay Races — Play some relay races that use Lego pieces. Some examples of different races you might choose include:
Lego Drop Relay — Divide your guests into two groups. Have the kids put Lego pieces under their chins and (one at a time) race from one end of the room to the other. At the end of the race they must successfully drop their piece into a bucket or bowl before the next racer can go. The first team with all its players back and seated wins.
Lego Spoon Relay — Divide your guests into two teams. Have the players race (one at a time) carrying a Lego on a spoon. If they drop the Lego they must stop and put it back before resuming the race. Have them go up and down stairs or walk backwards for an extra challenge. As a player nears his teammates, they must exchange the Lego piece from one spoon to the other without dropping it.The first team to have all its players back and seated wins.
Lego Drop Game — Set this game up by placing two kitchen chairs side by side with a gallon milk jug with the top cut off placed in front of each. Also place a container filled with legos next to each chair. Divide your group into two teams. Have them line up in two lines across the room from the chairs. At the start signal, have members from each team race one at a time to their group’s chair, pick up a Lego, stand on the chair and try to drop the Lego into the milk jug. Make this a timed activity. See which team succesfully gets the most pieces into their jug in the specified amount of time.
Lego Scavenger Hunt — Before the party, hide a number of Legos around your yard or party area. Assign each color a specific point value. For example, red Legos are worth 1 point, blue are worth 5 points, and yellow are worth 10 points. For the scavenger hunt, challenge your party guests to see how many Legos they can collect. At the end of the game have them count their pieces and total their points. Award a prize to the person who has collected the most Legos or who has collected the Legos with the highest total point value.
Lego Wii and Board Games — If your party is small, a fun Lego party idea might be to incorporate one of the many Lego games available. Here are some you might consider:
LEGO Champion Game
LEGO Monster 4 Game
LEGO Wii Star Wars
LEGO Wii Harry Potter
Lego Party Ideas for Food and Lego Cake!
Why not keep with the Lego party theme and serve only square or rectangluar foods? Believe it or not, this is easier than you think. Here are some suggestions:
- Bake rectangular pizzas and use pepperoni for the Lego knobs
- Cut carrots into square slices and serve with dip
- Make a tray of square crackers (such as Triscuits or Cheez-Its) and cheese cut into square slices
- Starburst and Jolly Rancher candies are both Lego-shaped and make good favors
