Big Builder appears to be an educational game, as it was produced in part by the Ohio State University Research Foundation and is an "Industrial Art Curriculum Project," according to the box. In the game players move around a set of different tracks in an effort to bid on and complete major construction projects (e.g., a bridge, a dam, etc.). Each player will end up with a different set of costs and savings and can choose the profit margin that they will use to bid for each project, although they are also limited by their bonding capacity - this is $250K at the start of the game and the object is to end up with the largest.
