Bridge Builder

About the game

Bridge Builder hands you a set of materials and a gap to cross. You draw the structure, pick what goes where, then let a vehicle roll over it and find out if your design holds or folds.

Four locations bring their own layouts, and the puzzles ask for logic more than speed. When a span keeps collapsing, a hint system nudges you toward a fix. The undo key gets a workout.

How to play

• Hold and drag with the left mouse button to draw bridge parts.
• Press Space to start the simulation and watch the vehicle cross.
• Press Z to undo; double-click a part to delete it.
• On a touchscreen, build and test with the on-screen controls.
