A river divides the town of Konigsberg into four separate land areas. Seven bridges connect the various parts of town (see diagram).
Some of the town's curious citizens wondered if it were possible to take a journey across all seven bridges without having to cross any bridge more than once. All who tried ended up in failure.
Try it yourself. You may start anywhere.
Why is this not possible?
