  • Euler finds out the solution
  • Graph theory never gets invented
  • We never have telecommunications or GPS

  A problem with this is that the river presumably goes all the way around the earth. Otherwise you could just travel west until you found its end. You really need a donut shaped earth, a sphere doesn’t help much

    But the river running round the whole planet does not matter in this case.

  Crossing oceans, which are continuous with the river, seems to make this about as meaningful at tunneling under the river.

    I feel that leaving Koningsberg is already breaking the rules.
