Bridge & Steam Physical Puzzle is a challenging bridge building game with realistic physics.

Construct railroad bridges using different materials: wood, steel, reinforced steel, ropes and balloons. Polish your creation until a steam train can pass safely. Avoid building simple box constructions, place X or \ inside the box so that it becomes stable. Watch out for blue and red stress on bars while testing, or the bridge can fail.

You can erase bars one by one. Just activate the remove button "X" and, while it is still active, tap on a block to delete it.

Enjoy 25 levels, and keep an eye out for the new ones!
