LEGO is a construction toy system made of small, colorful plastic bricks that snap together. The bricks connect with a satisfying click, and once joined, they hold firmly until you pull them apart to build something new.

The LEGO company started in Denmark in 1932, originally making wooden toys. In 1958, they invented the modern plastic brick design that's still used today. What makes LEGO special is that any brick ever made still works with every other LEGO brick, even ones from decades ago. This means the set your parent played with as a child can combine with one you buy today.

With LEGO, you can follow instructions to build specific models like spaceships, castles, or detailed replicas of famous buildings. Or you can create your own designs from imagination, which many builders find even more rewarding. Some people collect LEGO sets their whole lives, and there are even professional LEGO builders who create massive sculptures and displays.

The company also makes LEGO Technic sets with gears and motors for building working mechanical models, and LEGO Minifigures, the small plastic people that populate LEGO worlds and have become collectibles in their own right.
