Build a bridge with puzzle pieces and jigsaw, great mental game and skill.

Build the puzzle using your skills and taking into account the physics of each component, so that the train can reach the other side of the cliff. Beware of each item or piece you choose to build , as each has its own physical characteristics of mass and weight . Watch the wind and its direction for lifting the bridge.

Do not waste time and remember that the train must pass before the sun sets !
