LEGO® is a line of toys featuring colorful plastic bricks, gears, minifigures (also known as minifigs), action figures, and other pieces which can be assembled to create models of almost anything imaginable. Cars, planes, trains, buildings, castles, sculptures, ships, spaceships, and even working robots are just a few of the many things that can be made with LEGO bricks. Even movie themes and sagas have been introduced as sets. High production quality and careful attention to detail ensures that LEGO pieces can fit together in myriad ways, which is one of the main reasons for the toy's success.
The sets are produced by the LEGO Group, a privately-held company based in Denmark.
