Bridge Constructor Medieval - Complete puzzle solution to Chapters 3 and 4

Bridge Constructor Medieval is a physics-based puzzler that tasks you with building bridges over big chasms or choppy rivers.

Your bridges will have to be strong and stable enough to withstand soldiers and horse-drawn carriages, and fend off cannonball fire.

Plus, these chapters will see you making intentionally flawed bridges to send enemy troops to their death.

This guide will show you the optimum bridge design for each level. The different bridge bits are colour-coded: green for wooden planks, light blue for logs, yellow for stone, dark blue for rope, and purple for roofs.

By emulating any of the images on this page, you'll finish both objectives in each stage, which will earn you gold crowns and let you unlock bonus levels.
