Classic LEGO Bricks, Plates, and Tiles can be stacked vertically by attaching the round studs with a small amount of pressure.
Panels, walls, doors, and related parts make it easier to construct models than using bricks and plates alone.
These parts allow you to attach studs facing outwards (Studs Not On Top) or attach studs at an offset from the normal grid.
Slopes, wedges, and windscreens allow you to include angled sections in your model.
Build streamlined or organic shapes using a rich palette of curved parts.
Parts that bend or rotate, allowing for a wide range of interesting building techniques.
The classic LEGO Minifigure and Friends Minidoll live in a rich world of clothing, accessories, weapons, and containers.
Plants, animals, teeth, tails, and elemental forces bring the LEGO world to life.
Wheels allow your model to move, brackets make them stronger, noses make them look faster, and tracks give them somewhere to go.
Technic is a system unto itself, with a focus on connecting parts using pins and axles, but you will find plenty of Technic parts with studs as well.
Add light and motion to your creations using LEGO hubs, motors, lights, and sensors.
The larger bricks for younger kids are twice as big in each direction and compatible with regular LEGO bricks.
