What happens when a die picks your train?
In Gleiswürfeln, a die decides which train you take and where you get off. I turned the Swiss railway game into an app and connected the die to the timetable. That’s why every roll lands on a train that is actually running right now. Over 1,300 people have downloaded the app so far.
