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.
Seven Bridges comes with 80 towns and more on the way. The towns start off easy, build slowly, and end with a few tough ones.
Seven Bridges is a fun way to exercise your brain and perfect way to pass the time in boring meetings or the train ride home. It's also all open source. You can try it out for free, see the code, and take the whole game apart.
