Little bricks. Big ideas. Build, explore and become an inventive engineer.
Easy → intermediate → advanced → technicalThis is a simplified puzzle test: connected beams transfer the load to ground-supported columns. It is not real structural engineering.
Connect three gears. Change tooth counts, turn the motor on, and watch direction and speed travel through the train.
An ideal external gear model: adjacent gears turn in opposite directions. A larger output gear turns more slowly and increases torque. The middle gear changes direction, but not the overall speed ratio. Real mechanisms also have friction and losses.
There is no timer. Undo is always available. Try a symmetrical garden, a colourful skyline, a tiny robot, or a bridge with a different support pattern.
Keyboard: focus inside the studio, then use arrow keys to move, Enter to place, R to rotate, and brackets [ ] to change layers. Keyboard commands are paused while editing form fields.
