Link by Bixby Apps

Link is a physics puzzle game where you build railroad bridges across canyons, rivers, and valleys, then send a train over them to see if they hold. HOW TO PLAY 1. Pick a level. Each level shows a gap in the railroad line, the anchor points you can build from, and a limited supply of building materials. 2. Choose a material, tap an anchor point, and drag to place a girder. A green circle means the connection is allowed. A red circle means it is not (for example, you can't build underground). 3. Keep adding girders from anchor points and existing girders until the track reaches the other side. Triangles are more stable than squares, and heavier materials add weight to the bridge. 4. Tap Play to send the train across. The bridge is simulated with physics, so girders bend under the load and weak joints can break. 5. If the train makes it across, the level is complete and you get a score. If the bridge collapses, go back to building, fix the weak spots, and try again. Your score is higher when you have more materials left over and the bridge carries the train with less stress. BUILDING MATERIALS - Wood girders: lighter than steel. - Steel girders: stronger, but heavier. - Rope cables: hang the bridge from anchor points above it. - Stone blocks: stack on level ground to raise an anchor point. FEATURES - 100 bridge-building levels with different gaps, terrain, anchor points, and material limits - Physics-based simulation of the train and every girder in your bridge - Analyze Stress tool that colors girders yellow, orange, or red to show where the bridge is under the most strain - Heavier cargo cars on some levels, such as loads of bricks and large stone heads - Tradin' Post on some levels, where you can exchange one material for another at set rates - Levels where you choose your own anchor point positions - Undo, delete, reset level, zoom in and out, and a building grid you can turn on or off - Pause the train during a test and go back to building at any time - A saved score for each completed level, shown on the level select screen - Take a snapshot of a finished bridge and share it - Help screens and a short tutorial on the first level GOOD TO KNOW - Free to download. The first 5 levels are free to play in any order. - A one-time in-app purchase unlocks all 100 levels. It is not a subscription, and Restore Purchases is available. - No ads. - No account needed. The game plays offline. An internet connection is only needed to buy or restore the unlock and to share snapshots. - Landscape orientation on phones and tablets.
