About
Span is a calm, physics-driven bridge builder. Draw a bridge across the gap, choose your materials, then press Test and watch it carry the load — or buckle in glorious slow motion.
Every beam glows with the forces running through it: a live X-ray of tension and compression, so you can see exactly why it held, or why it snapped. Rewind, move one strut, try again.
• 57 hand-built levels across eight worlds — timber valleys to ocean straits
• Timber, steel, stone, cables and road & rail decks
• Real hazards: wind, earthquakes, thermal stress and floods
• Drawbridges, canal locks, trains and passing ships
• God-mode Sandbox: unlimited budget, every material, every disaster
• Level editor: sculpt terrain, place anchors, schedule the traffic
• One-tap replay export — share your best holds and worst fails
No ads. No timers. No subscription. Buy once, build forever.
Free through Chapter 1 — unlock the full game (all worlds, the sandbox and the editor) with a single purchase.
