The Clickety Bricks builder: a brick-built excavator, the parts list on the left and the colours on the right

Everything a LEGO® builder wishes their table could do

Real parts, modelled

Over 20,000 digital models of real parts: bricks, plates, Technic beams, gears, wheels and minifigures, in the colours they're actually made in.

Snaps like the real thing

Studs click onto tubes, pins into holes, axles through gears. No fiddly lining up.

Machines that run

Add a motor and press Play: gears mesh at the right speed, linkages swing, worms lock and walkers walk.

Will it work?

The Check tab finds gears that jam, parts that collide and builds that would fall over, and tells you how to fix them.

Instruction booklets

Turn any build into step-by-step instructions with parts lists, ready to print as a PDF.

Photos and videos

Lifelike photos and videos of your machine in motion, ready to share.

Press Play and watch it move

Every gear, rod and pin is simulated. The app shows how fast each part turns, how far each arm swings, and exactly where something would jam.
