If these tickets are not completed by the end of the game they will count against you. So grab Destination Tickets conservatively.
Completed Tickets are only scored at game end so do not announce upon completion of your routes. This adds a bit of mystery to the game and makes for a thrilling game of blind competition.
DON'T FORGET TO MOVE YOUR SCORE MARKER. It makes for a quicker scoring at the end of the game.
Destination cards and Train cards are kept secret throughout the game. Destination tickets are revealed at the end of the game to add or take away points based on if the my were completed or not.
In case of a tie the player with the most train cards left is the winner. If there is still a tie the player with the longest continuous path between the two wins. If its a tie still then it's a tie.
