Pencil Bridge

Engineer a truss that survives the truck. One flat plank will sag and snap — you must triangulate.

• ✏️ Drag to sketch beams. Each beam has a max length — long spans need joints & triangles to stay rigid.
• ⚠️ Limited graphite budget. Overloaded beams glow red, then SNAP — and the truck plunges.
• 📚 From level 2, obstacles rise from the chasm — you can't draw through them, so arch over or route around.
• 🚚 Each level the gap widens, the truck gets heavier & faster, and wind picks up. Clear as many as you can!
