Imagine Bridge Constructor with a default free-build mode and each level offering five challenges to master. That is the concept of Bridge Constructor Playground! Tackle each level without constraints and freely build your bridges to move on to the next level. If you want to enter the next island, however, you have to bring a number of badges that can be earned in the levels. The badges belong to different categories that offer different challenges: safety badges demand to stay below a certain maximum stress amount, whereas material badges require the use of only certain materials. All in all, the game offers 160 challenges to master on four islands! Source: The Developer Website.
