The "Bridge Constructor" follows a simple game principle: With a fixed budget choosing from building materials such as stones, ropes and different thick planks, the material for a bridge that will withstand a certain load at the end. The graph is designed very simple and could so easily can look even ten years ago, also lacks assistance, which quickly accumulates frustration. On top of that the price but seems rather high, even those who have an affinity for games of this kind, gets 40 levels not too large scale offered.
Hence my conclusion: The price-performance ratio is unfortunately below the average, which is why I recommend to look for other alternatives if you are interested.
