Pass the Lego
Play the game like Hot Potato, but have players add a Lego brick each time it gets to them.  Keep going until one player is left.  Don’t get caught with Lego sculpture when the music stops!

Lego Charades
Write simple sculpture ideas down on cards or pieces of paper.  Provide a bucket of Legos to work with, and give each player or team 10 minutes to make their sculpture.  Have players guess what the sculpture is and give prizes for the winner!

Tallest Tower
Divide the group into teams.  Give each team a big pile of bricks and see who can build the tallest tower in 5 minutes.

Lego Building Contest
Let each party guest build their own Lego creation.  Provide a big pile of bricks and accessories (doors, windows, and other oddly shaped Legos) to work with, give them a good amount of time to work with, and enjoy the silence!  Let them admire each others designs, and give prizes for different categories (suggestions – tallest, funniest, best details, fastest work, most creative, most colorful, etc.).   You can also give out Master Builders certificates to all (this one is from How to Cook That).

Guess How Many Legos
This is a good one to have guests do as they arrive at the party.  Place a clear container full of bricks on a table and have kids guess how many Legos there are by filling their answers out on a sheet of paper or on slips of paper.  Announce the winner at the end of the party.  Be sure to count the Legos yourself first!

Lego Bingo
Print out free Lego Bingo cards and use Lego bricks as the markers.

Lego Car Races
Provide car parts (wheels, car bases, seats, steering wheels, windshields, etc.) for the kids and let them make their own vehicles.  Make a ramp out of a plywood sheet (as simple or elaborate as you want to make it), and let the kids race their creations to the bottom.
