Board games such as Ticket to Ride by Days of Wonder use game boards which are based on real geographic data. In this particular example the game map is an abstract railway graph consisting of a set of train stations, that are connected by train routes. Generating such maps by hand is a long and time consuming process. Therefore we present an algorithm that can generate playable maps for the game Ticket to Ride for different countries and continents. The result of this work is an application which is able to automatically create a game graph using OpenStreetMap data as input. We try to keep the generated graph as similar as possible to the original game in terms of important metrics that affect the gameplay, while trying to keep the result close to the geographic data during the abstraction process. The result is exported into a format that can be imported by an open source web version of Ticket to Ride, which allows players to play on the generated map.
