A new roll-and-write game for 1-6 players called Seven Bridges is going to hit Kickstarter on September 24.
The game features an actual map of the old city of Königsberg (now Kaliningrad), drawn by a professional cartographer. Your goal is to score points by drafting dice and sketching routes on the map. Most points are scored if you manage to cross all seven bridges, and also visit landmarks like a very determined tourist.
The mathematical problem the game is inspired by was 'to devise a walk through the city that would cross each of those bridges once and only once' (from Wikipedia). Leonhard Euler proved that the problem had no solution. He clearly didn't try to roll-and-write it.
