From the announcement:
Representing the USA, Kenneth Heilfron is officially declared the 2014 Ticket to Ride World Champion as the previously announced champion, Erwin Pauelsen has resigned his title.
After more that 25,000 contestants played around the world, Days of Wonder gathered the 28 National Champions in Issy-les-Moulineaux near Paris, France for the final stage of the Ticket to Ride World Championship tournament. After 3 qualifying rounds, the top 8 then played a succession of head to head games for quarter, semi and then championship games. Erwin Pauelsen appeared to have won the final match and was awarded the Golden Train Trophy.
However, quickly after the event ended, contestants and Ticket to Ride fans from around the world (who were able to follow the tournament live on the internet) voiced concerns about possible irregularities during the final game.
Days of Wonder closely examined the final matches and unfortunately found evidence of cheating during the 2nd game of the final. Mr Pauelsen has admitted to his dishonesty and agreed to hand back his title and trophy.
