Your goal is to build a bridge that can withstand a train running over it. The circles are the points where you'll connect to solid ground. Click on one to draw a line from it. Lines drawn along the ground level will become the path and any other lines will become support beams. Each line costs 100 units regardless of length and the bridge's cost may not exceed the total budget shown in bottom left corner. WASD to scroll, QZ to zoom, shortcuts to other functions as shown on the buttons on screen. Right-click to remove elements, or drag to select an area then press delete.

Press Test to test the bridge. Press (Max) Stress to display the amount of force exerted on each part. Red denotes compression, blue tension. Press Run Train to run the train. The level is considered cleared if the train successfully passes, even if the bridge is destroyed behind it. If you fail, press Edit to go back to editing, then you can press Stress in the editor to display the last shown forces in the editor. If you succeed, you'll see "Test Passed" and a Next Level button will appear which takes you back to level select, with the next level now selectable.

For basic strategy, have your support structures consist of triangular shapes and prefer as long beams as possible. Test early and often and reinforce your bridge where it fails.
