Build a Bridge! is a complex yet approachable physics-based puzzle game. It tasks the player with creating more and more elaborate bridges across multiple levels. You will have to choose the proper materials, using creativity and logic to stay within required budget and create a strong construction. During the planning phase the game presents itself with a simple, 2D interface. It is there that you select the best materials for your bridge and connect the dots to make the most resilient structure you can. You can approach each level as a complex puzzle, trying to be as efficient as possible and get the best solution. But don't be afraid to experiment too. You can just go crazy and construct something that looks outrageous but still somehow works. There's fun in both of these approaches. When you're done, switch to the 3D mode and watch a car drive through your bridge. Will it hold? Or will you watch a spectacular crash? In addition to the normal mode the game features the easy mode for more relaxed gameplayed, focused on creativity and improvisation. You can also use in-game hint system if things get too hard. With 86 levels to construct you will not run out of things to do quickly. Game features: - Different materials to build from - Wood, Metal, Cables - 86 levels of increasingly difficult puzzles - Varied, detailed environments full of interactive elements - Multiple cars to test out your constructions - Realistic physics engine - Beautiful, stylised art style - Available in 13 languages IGRS rating: 13+

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.
