About this app

The rules are simple. The game isn't. You're visiting towns full of rivers. The rivers form islands with bridges connecting them. To beat the game just cross every bridge once and only once. Each town challenges and entertains you with twists, turns, and a little man walking across bridges. The towns start simple and add more and more with houses to visit, colored bridges, tolls, and subways. Bridge - River Crossing IQ comes with 80 towns and more on the way. The towns start off easy, build slowly, and end with a few tough ones. Bridge - River Crossing IQ is a fun way to exercise your brain and perfect way to pass the time in boring meetings or the train ride home. Bridge - River Crossing IQ The city of Konigsberg in Prussia (now Kaliningrad, Russia) was built around two rivers with seven bridges. For years the residents tried to cross each bridge without crossing any of them more than once. Leonhard Euler proved that it was impossible to cross all the bridges without repeating and laid the foundation for graph theory and modern topology at the same time. This project is an iPad and iPhone game based on those famous bridges. Each level presents a puzzle with bridges to cross, houses to visit, and sometimes coins to collect. Have fun!
