Touchscreens have proven fertile ground for physics-based puzzle games. While slingshot-knocking, match-3-dropping, ragdoll-flinging titles tend to dominate the genre, we love one game in particular for abandoning the formula and letting players partake in - you guessed it - bridge building.

Bridge Constructor will have you managing budgets and selecting building materials in an attempt to get vehicles across gaps of increasing sizes. The game's refreshing simplicity and challenging learning curve make it the perfect hump-day app.
