Span vs Tower Builder

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.

Can your tower survive a magnitude 10 earthquake? Tower Builder is a physics-based earthquake simulator game: design towers, cranes and bridges beam by beam, then shake them with real quake physics. BUILD WITH REAL PHYSICS • Four materials: rope, wood, concrete and steel, each with its own strength, weight and cost • Every beam carries real load, so triangles and cross-braces matter • Hold heavy cargo, beat strong wind and stay on budget SURVIVE THE QUAKE • Earthquake sectors from small tremors up to magnitude 10 • Watch beams bend, glow red and snap in real time • Fail, learn, rebuild: every collapse teaches you a little structural engineering NEW: BUILDING DEMOLITION MODE • Brand-new building demolition levels • Place explosive charges, bring the structure down and keep the neighbours' houses safe • Earn three stars with a clean, controlled collapse GROW YOUR CONSTRUCTION COMPANY • Upgrade your rope, lumber, cement and steel factories at Company HQ • Unlock stronger materials and bigger contracts PLAY ANYWHERE • Works offline: no internet needed to play • Free to play with short levels, perfect for quick sessions If you enjoy bridge builder games, construction simulators, physics puzzle games or earthquake simulator games, Tower Builder is made for you. Build it. Then shake it!
