Bridge Builder is a puzzle video game series, created by US-based indie developer Alex Austin. Bridge Builder being the first in the series, it was followed by four sequels in different versions, all of them developed and published by Chronic Logic, the only exception being Bridge Project, which was developed by Halycon Media and Caipirinha Games, some of the games also feature secondary publishers.
The objective of each game is to construct a bridge which a train may cross over, given a limited budget and materials.
Each level is composed of a section of land, such as a river or chasm, and an initially laid track that shows the train's starting and ending points. A number of anchor points in and around the chasm are where the player anchors the bridge from. Should the player's train cross the bridge successfully and under budget, the level is passed. Later games add additional constraints such as a boat that must pass underneath between two consecutive train crossings.
Although Bridge Builder only allows the player steel beams, bridges in later installments can be created using a variety of materials. Along with varying strengths of steel, the player can also use cable or hydraulics that expand or contract for some purpose, such as to allow a ship to pass underneath the bridge. In all games, the player is constrained by a budget that determines the maximum amount of material that can be used and still pass the level.
There is no penalty for failing a level; the player may try and test infinitely many different designs before finding one that succeeds. A poorly designed bridge may break as soon as the player begins to test it, unable to support its own weight. While testing the bridge, the stress on each section can be seen, representing both tensile stress and compressive stress. If the stress becomes too great, that section breaks and disintegrates, possibly jeopardizing the entire structure.
