As title says, BRIDGE! The Construction Game is a game about building
bridges across stream of water and not getting wet, similar to Pontifex
series.

In each mission, player has to link road ends at river or harbour banks. For
this, limited amount of various materials and certain sum of money are
granted. The field, separated into 1×1 meters net, allows to connect parts
freely, where joints can be one of three types: fixed, with sections rigid
connected; break, without any connection at all; and rotating joint, when
parts can rotate around axis. Wide components specter gives access to many
sorts of road sections, girders, hydraulics and cables. Utilizing that rich
choice, player is challenged to build truss, suspension, bascule, cable-stayed
and other bridge types up to 300 meters long.

The main campaign consists of thirty levels, ten for each difficulty type
(easy, medium, hard), with number of goals at the end. Basically, they are
separated into traffic related tasks and natural disaster endurance: traffic
might be cars, train or ship; disasters are presented with flood, earthquake
and windstorm, each of three power tiers. At any moment, simulation mode can
be turned on in order to test stability and perform trials. After successful
completion, player receives new parts for free editor mode, which doesn’t
restrict anything and allows to place anchors, pillars, to change bridge
height, length and, if constructed building withstands selected test, to save
custom missions and share them with other players.
