Poly Bridge is a really fun iOS app. It's part puzzle game and part bridge builder. There are 100+ levels that you must walk through as you figure out the best path forwarding. It's one of those game that you grow to love and hate all at the same time! Your goal is to finish the bridge under budget while remaining stable. Do you have what it takes?

After you finish all the levels, you can then head over to to sandbox mode and build your own!

Get it on the App Store for $4.99.
