Build anything with gears in it
Over 200 parts, and the mechanical ones are the point: motors, gears, pulleys, joints, springs and actuators that all actually work together. Build a car with rack and pinion steering and a differential, or go further and assemble an engine from pistons to output shaft, transmission included. Snap parts together, resize them, change materials, paint them, and link their behaviours. The store's own examples set the bar: a parkour course with motorised bouncy platforms, or an unstoppable walking mechanical elephant. The only limit is your imagination, and physics, which has opinions.
Turn it on, grab it, break it
Your machines are not models on a shelf. Turn them, grab them, shove them, and watch the parts physically interact. This is where the sandbox earns its chaos: builds that took hours can fold spectacularly in seconds, and that is part of the fun. When something breaks, you learn something. If it refuses to break, you have built something genuinely solid.
