Equipment: A big tub or bag full of Legos.
Basic game: Each player closes his eyes, reaches into the tub, and grabs a handful of Legos. He has to build something with whatever he's ended up with. When both players are done building, they have to explain what they've made.
Variation 1: The players all agree on what they're going to build (car, treehouse, washing machine) before they grab their Legos. This can get really fun and creative. For example, when you have two minifigs, a wheel, and a tree and you need to build a submarine.
Variation 2: Each player gets to tell another player what to build before they grab their Legos. This makes the game a little more competitive. My six-year-old likes this version of the game.
Build, create, have fun!
