how to play Ticket to Ride - the Dice Expansion

About Ticket to Ride: The Dice Expansion, from BoardGameGeek:

In this expansion for the Ticket to Ride series, players still attempt to complete their Destination Tickets and claim routes and block each other on the map. But rather than draw and collect Train cards, they roll five custom Train dice each turn. Depending on the outcome they can re-roll some or all, then use the dice to claim routes on the board; grab Route Tokens for future use; or draw more Destination Tickets. For board maps that feature Tunnel routes, such as Ticket to Ride: Europe, 3 Tunnel dice are also included. This expansion requires trains, Destination Tickets and a board map from any of the Ticket to Ride series.
