Difficulty: EasyPuzzle Details

The river Pregel runs through the town of Konigsburg. In the river are two islands, connected to each other and the rest of the city by seven bridges. The students of Konigsburg often challenge each other to try to make a trip crossing all seven bridges exactly once - can you find the path they have to take in order to do this?
